jedesa> hey

jedesa: kin kon kan kon amigojapan Haniibooru 

amgigojapan: hey jedesa !

amgigojapan: jedesa: one sec

amgigojapan: lol jedesa , that was funny

amgigojapan: jedesa: shall we start?

jedesa: ok amigojapan 

jedesa: what are we learning today?

amgigojapan: jedesa: well, let me look at my notes

amgigojapan: jedesa: programming lessons, next up operator priority, string handling, classes, recursion 

amgigojapan: jedesa: form easiest to hardest order

amgigojapan: jedesa: I think recursion can take up a whole lesson on its own

amgigojapan: and we may need to borrow some form my Think Like a computer lessons for it

jedesa: hmm

amgigojapan: jedesa: ok, so are you ready?

jedesa: what's a Think Like a computer?

jedesa: a youtube channel?

amgigojapan: jedesa: it is a board game I am making to teach programming, I had not told you about it yet

amgigojapan: jedesa: I have not published it yet

amgigojapan: jedesa: its nto finished

jedesa: Oh okay

jedesa: by the way

amgigojapan: yes?

jedesa: I have spend a little of time glossing over some fundamental programming concepts

jedesa: hopefully I could follow without much trouble

amgigojapan: ok, do you know what operators are? and what their priority is?

jedesa: hmm, symbols like +, -, AND, OR .. ?

amgigojapan: yes

amgigojapan: do you know the priority?

amgigojapan: jedesa: like if you do 2*2+1 whats is the difference between that and 1+2*2?

jedesa: not really, for any specific language

amgigojapan: jedesa: this is generally the same in every language

jedesa: I mean for arithmetic * takes precedence

amgigojapan: yes ok, yes

amgigojapan: then you know it

amgigojapan: jedesa: did you know that you can surround the operations in parenthesis to change the priority?

jedesa: yes

jedesa: so like

amgigojapan: ah ok, let me mention it for the other people that may be seeing the lesson later

amgigojapan: like say 1+(2*2) is the same as 2*2+1

jedesa: yeah, I should like to know what you know too

amgigojapan: well, thats it for operator priority, if you are eve in doubt, just surrounding it by parenthesis so you know what goes first

jedesa: Okay

amgigojapan: jedesa: ok, so I guess we can go on ot string handling

amgigojapan: jedesa: so a string is something like str="abc"

amgigojapan: jedesa: in python if you want to "concatenate"(connect two stings) a string one way to do it, it to use the + sing, like this str = "abc" + "def"

jedesa: I see

amgigojapan: jedesa: you can do it inside a print statement too like this print("hello " + name)

amgigojapan: jedesa: name being a string variable

amgigojapan: jedesa: why don't you make a small exercise, getting input form the user asking him his name, and outputting hello and then their name?

jedesa: Yeah, okay

amgigojapan: :)

amgigojapan: then link me the code

jedesa:

print("what is your name?")
name=str(input())
print("hello " + name + "!")

amgigojapan: let me see

amgigojapan: perfect jedesa !

jedesa: yay!

amgigojapan: jedesa: thats how i greet people on the BBS

amgigojapan: jedesa: now, look at the following code:


main_string = "Hello, world!"

substring = "world"


if substring in main_string:

    print(f'"{substring}" was found in the string.') # Output: "world" was found in the string.

else:

    print(f'"{substring}" was not found.')


jedesa: I see

amgigojapan: yeah

amgigojapan: so that is how you can verify if a substring , a string is found inside another string

jedesa: so string is made of bunch of characters, with that you can add or subtract it as well

amgigojapan: jedesa: then in python you have str.find()  to find a substring position in a string, this is quite useful, because I will teach you how to use the position soon

jedesa: Okay

amgigojapan: jedesa:no, this is separate form the lesson of operators, string is only a bunch of characters

amgigojapan: adding a string to another string in python is called "concatenation" and in python it happens to be + that does it, but ti is not math

amgigojapan: like in PHP concatenation is done by using . not +

jedesa: hmm I see

amgigojapan: so in PHP you would do $str = "abc" . "def";

amgigojapan: yeah

amgigojapan: but lets worry about PHP later

amgigojapan: jedesa: in python  and JS it is + in LUA it is .. and in PHP it is .

amgigojapan: but they are still similar

jedesa: . .. + are all operators in their respective language

amgigojapan: yes jedesa 

amgigojapan: jedesa: now try this code:


text = "Hello, world!"

position = text.find("world")

print(position)  # Output: 7


jedesa: Okay

jedesa: so 7 is from the length of "Hello, "

amgigojapan: jedesa: now this is very useful, cause if we know the position of a substring in a string we can do many operations on it

jedesa: do we have some examples?

jedesa: I don't feel any ideas for now

amgigojapan: yes exactly! jedesa now try a small exercise and show me if you can make a program that finds out if someone's name contains the letter a

amgigojapan: jedesa: and if it does, let me know which position of the word it is in

amgigojapan: jedesa: ok, I will make an example meantime

jedesa: 

# https://www.programiz.com/online-compiler/3zEZ7Dtxl2FHy

substr="a"
print(f'"what is your name?"')
name=str(input())
print(f'"{substr}" is at position {name.find(substr)}')

amgigojapan: jedesa: it is useful cause for example:


text = "I love Python" 
new_text = text[:2] + text[7:]
print(new_text)
#output is "I Python"

amgigojapan: will remove the world love form that new variable

amgigojapan: let me see

amgigojapan: ok that works jedesa , although notice if the name does not contain a, it will return -1

amgigojapan: which means "it was not found"

jedesa: Yes

jedesa: It could be added for handling non-existing word

amgigojapan: jedesa: now, make a program that takes input form the user for a string1, then and input form the user for a string2, and deletes the word form the string and prints the result

amgigojapan: yup

amgigojapan: take your time

jedesa: hmm?

amgigojapan: any questions?

jedesa: delete a substring in string1, based on input of string2?

amgigojapan: yes

amgigojapan: jedesa: oh I forgot to teach you a necessary component for that program

jedesa: actually let me try

amgigojapan: jedesa: len(string) gives you the length of a string

amgigojapan: do you need a hint?

jedesa: 

# https://www.programiz.com/online-compiler/2HhtjMY99LFzU

print("input string1")
string1 = str(input())
print("input string2")
string2 = str(input())
pos = string1.find(string2)
while pos > -1:
    string1 = string1[:pos] + string1[pos+len(string2):]
    pos = string1.find(string2)
print(string1)

amgigojapan: let me see

jedesa: This should do it

amgigojapan: yeah it works! jedesa :) great!

amgigojapan: jedesa: now make a program that takes 3 strings, similar to this program, but now the third string should take the place of the word that was deleted

jedesa: Okay


# https://www.programiz.com/online-compiler/31ZQbvUMBRE3C

print("input string1:")
string1 = str(input())
print("input string2:")
string2 = str(input())
print("input string3:")
string3 = str(input())
pos = string1.find(string2)
while pos > -1:
    string1 = string1[:pos] + string3 + string1[pos+len(string2):]
    pos = string1.find(string2)
print(string1)

#example output
input string1:
HELLO WORLD BYE
input string2:
WORLD
input string3:
MARS
HELLO MARS BYE

jedesa: wow, fast

amgigojapan: let me see

amgigojapan: nice jedesa !

amgigojapan: jedesa: I think you have the basics of string handling now :)

jedesa: print("ehehe")

amgigojapan: :)
amgigojapan: jedesa: I could give you a hard homework on string handling, if you want

jedesa: alright

jedesa: hold on

jedesa: we still have classes and recursion

jedesa: hmm okay

amgigojapan: jedesa: ok, don't do it now, it will take too long, but homework is, make the hangman game, using string handling 

jedesa: I see

amgigojapan: jedesa: yeah, recursion can come later, and I don't think we have time for classes today

amgigojapan: jedesa: you can take a whole week to do this homework

jedesa: I'll give it a try later

jedesa: okay amigojapan 

— jedesa kin kon kan kon

jedesa: yes, thanks for your time today :3

amgigojapan: thanks for your time too!
