How to print input through texts (Python)

Question

I want my program to print the value of the variable 'sob' when I write: write("sob")

Code:

str = input(">")
sob = input(".")
if str == ('write("' + sob + '")'):
    print(sob)
else:
    print("SYNTAX ERROR")

Yes, so if the user writes 'write("sob") and the user presses enter then it will display sob. Or any word they write between the brackets. — MLCLOUD, Jul 01 '16 at 02:11

Instead of using input() use raw_intput():

str = raw_input('>')
sob = raw_input(".")

if str == ('write("' + sob + '")'):
        print(sob)
else:
        print("SYNTAX ERROR")

input() interprets the input you enter as python commands, whereas raw_input() returns a string.

Is there a way I can write input() with nothing in there – MLCLOUD Jul 01 '16 at 02:16
@MLCLOUD What do you mean "with nothing in there"? – user3814613 Jul 01 '16 at 02:18
@user3814613 it depends on which version of the Python the OP is using `input()` is correct for Python3. – AChampion Jul 01 '16 at 02:25
Can I write input(">") as input()? – MLCLOUD Jul 01 '16 at 02:31
@MLCLOUD Yes you can, but in this case you should probably use `raw_input()` instead of `input()` – user3814613 Jul 01 '16 at 02:34
Yes, the prompt is optional. – AChampion Jul 01 '16 at 02:35
@user3814613 Again you might want to validate which version of python the OP is using before offering potentially erroneous information. Given the OP is using `print()` this is a python3 construct (unless using `__future__`). – AChampion Jul 01 '16 at 02:36
Is it optional? Dosent seem to be, or maybe something in my code messed it up? – MLCLOUD Jul 01 '16 at 02:37
@AChampion Thanks for the advice. I'll definitely keep that in mind in the future. – user3814613 Jul 01 '16 at 02:37

Try this

CODE

sob = raw_input('Type write("sob"): ')
sob = sob.lower()
if sob == 'write("sob")':
    print(sob.lstrip('Type write("').rstrip('")'))
else:
    print("Error")

RESULT

sob

I only want it to display the word sob – MLCLOUD Jul 01 '16 at 02:14
do you want the user to input 'write' or just 'sob' – Jul 01 '16 at 02:15
I want the user to input the whole thing but it only prints sob – MLCLOUD Jul 01 '16 at 02:16
@MLCLOUD updated again to make it safe against differences in capitalization. The second line casts the input as all lowercase before the comparison is made. – Jul 01 '16 at 02:32
Thanks! I will test to see if it works, does it work with python 3.x? – MLCLOUD Jul 01 '16 at 02:33
@MLCLOUD for 3.x just change 'raw_input' to 'input'. Raw_Input no longer exists in 3.x – Jul 01 '16 at 02:36
Oh yes i already knew that. Im actually building a mini programming language in python - zircon-lang.weebly.com – MLCLOUD Jul 01 '16 at 02:38
Thanks. Do u know how to make a loop so the user can write and print as much as they want. – MLCLOUD Jul 01 '16 at 02:49
Yes, this can be done. I just logged off for tonight. I'll post a solution tomorrow afternoon – Jul 01 '16 at 02:53
@MLCLOUD I asked a question myself that was similar. You should be able to modify this to fit your needs. http://stackoverflow.com/questions/37841115/python-input-prompt-go-back – Jul 02 '16 at 12:56
Thanks a lot mate! – MLCLOUD Jul 03 '16 at 12:46
