why doesn't = work in a while true loop python?-CodePudding

the code just doesn't work, I can not understand what is wrong with the =

taken = 1
first = int(input("   "))
while taken <= 6:
        print(1)
        print(taken =1)

the syntax error just pops up and the is highlighted red, I have tried looking however the only question I found was where it did not work because of the global the person put before the thing they were = onto.

CodePudding user response：

This is because variable = val is shorthand for variable = variable val
As this is an assignment expression, and doesn't return anything, that's why this is considered to be a syntax error.

Note 1: This has nothing to do with while loop, it's universally unaccepted

Note 2: Python doesn't support / -- operators as of now

So, do this instead:

taken = 1
first = int(input("   "))
while taken <= 6:
        taken =1
        print(f"1\n{taken}")

CodePudding user response：

you simply cannot do that. you can do this instead :

taken = 1
first = int(input("   "))
while taken <= 6:
        print(1)
        taken  = 1
        print(taken)

CodePudding user response：

This happens because you cannot reassign a variable in the print function Try to write taken = 1 in the row above and than print taken.

taken = 1
first = int(input("   "))
while taken <= 6:
        print(1)
        taken  = 1
        print(taken)
