Sometimes, we want to fix TypeError: unsupported operand type(s) for -: ‘str’ and ‘int’ when using Python input
In this article, we’ll look at how to fix TypeError: unsupported operand type(s) for -: ‘str’ and ‘int’ when using Python input.
How to fix TypeError: unsupported operand type(s) for -: ‘str’ and ‘int’ when using Python input?
To fix TypeError: unsupported operand type(s) for -: ‘str’ and ‘int’ when using Python input, we should convert the string returned by input
to an int.
For instance, we write
def cat_n_times(s, n):
for i in range(n):
print(s)
text = input("What would you like the computer to repeat back to you: ")
num = int(input("How many times: "))
cat_n_times(text, num)
We call input
with a string for the prompt.
And then we call input
to get the number entered by the user.
Next, we call int
to convert the string of the value entered by the user to an int.
Then we can use value n
in cat_n_times as an argument of
range`.
Conclusion
To fix TypeError: unsupported operand type(s) for -: ‘str’ and ‘int’ when using Python input, we should convert the string returned by input
to an int.
