TypeError: can’t multiply sequence by non-int of type ‘float’ error occurs when “you use the input() function, which takes user input”. The input() function returns user input as a “string” by default.
To fix the TypeError: can’t multiply sequence by non-int of type ‘float’ error, “convert the string into a floating-point number using float() function before multiplying it with a float”.
When you try multiplying a float and a value, not an integer or string, you will encounter a TypeError can’t multiply sequence by non-int of type ‘float’ error.
Reproducing the error
user_input = input("Please enter your age: ") print(user_input * 0.5)
Please enter your age: 18 TypeError: can't multiply sequence by non-int of type 'float'
How to fix the error
You can use the “float()” function to convert the string data type and multiply it with a float value.
import math # Get user input and convert it to a float user_input = float(input("Please enter your age: ")) print(user_input * 0.9)
Please enter your age: 34 30.6
In this code, we converted user input into a float and multiplied it by the float value. This way, you avoid the TypeError: can’t multiply sequence by non-int of type float error when working with user input.
