Python return back

[Spoiled_Kitten]

so in bat files you can do

x

*code go here*

go to x

and it will loop back to there, i wish to have this in my code for python 3 where if you have an option that the computer doesnt understnad then it will continue that section till it words, i tried to use while commands but i have a variable inside that cant be changed, so thats my major issue.

You're going to have to clarify this.

so the variable whenever i use the while statement, as soon as an answer my program can understand goes through, it disappears

If I understand correctly what you actually mean, you need to define the variable before the while-loop, like e.g.:

answer = ""
counter = 0

while True:
	#Insert code to do some useful stuff here
    counter += 1
    if(counter == 5):
    	answer = 42
        break

#answer was defined before the loop, so it doesn't "disappear", ie. go out of scope, after the loop exits.
print(f"The answer to the meaning of life is: {answer}")

This would be a lot easier for everyone if you just post a code snippet.

.....aaaand you never mention the error you get. Wow, that's very fucking useful.

 

I assume it's that print-clause where I use an f-string. Well, that's easy to fix: just replace the print-clause with something else! The print-clause wasn't the point there, the point was demonstrating how declaring the variable before the loop fixes the issue.

 

Also, quote people if you reply to them. I didn't know you had replied until just now, because you didn't quote and thus I never got a notification about it.

Aren't you just talking about using functions? You can use your variable as input for your function and also set your variable to the output of said function.

 

def myCoolFunction(input):
    functionOutput = input + 1
    return functionOutput

myCoolVariable = 1
print("myCoolVariable is: " + str(myCoolVariable))
myCoolVariable = myCoolFunction(myCoolVariable)
print("myCoolVariable is: " + str(myCoolVariable))
myCoolVariable = myCoolFunction(myCoolVariable)
print("myCoolVariable is: " + str(myCoolVariable))
myCoolVariable = myCoolFunction(myCoolVariable)
print("myCoolVariable is: " + str(myCoolVariable))

Output

❯ python3 function.py 
myCoolVariable is: 1
myCoolVariable is: 2
myCoolVariable is: 3
myCoolVariable is: 4

Your post is a bit vague, so maybe I'm way off the mark here.

#variables for word lists
wordlist1 = [""]
wordlist2 = [""]
wordlist3 = [""]
wordlist4 = [""]
 

#asks for name
name=input("What is your name?")

#capitalizes first letter of word and decapitalize other letters for name
name = name.capitalize()

#says a greetings
print("Hello", name, "Hope you enjoy!")

#ask what subject they want to do
print("What would u like? Mieliestronk's list of over 58,000 english words [Hard] or ?[option 2]")

#gets input for result
result = input("")

#capitalizes first letter of word and decapitalize other letters for result
result = result.capitalize()

#choices subject:
#To add more results copy one of the options and just change what is in the "" and after the words =

#option 1
if result == "Hard":
    print("You picked: Mieliestronk's list of over 58,000 english words ")
    words = wordlist1
    
    
    
#To add more results copy one of the options and just change what is inside the ""

#option 2    
elif result == "":
    print("")
    words = wordlist2
    
#option 3

elif result == "":
    print("")
    words = wordlist3
    
#option 4

elif result == "":
    print("")
    words = wordlist4

#if all fails terminates program

else:
    print("invalid option")
    print("please start ")
    quit()

 

 

Thats the snippet im having trouble with

The error is rather self-explanatory: fix your indentation.

You have both spaces and tabs for indentation in your code and you need to use only one or the other -- either replace all the tabs in your indentation with spaces, or all the spaces with tabs.

Use the Code tag for your copied code. That way it will paste with all the indentations intact.
