python TypeError: can’t multiply sequence by non-int of type ‘float’
This error shows up when there is a type mismatch.
Example:
When you execute below code you will get this error-
>> hrs = input(“Enter Hours:”)
Enter Hours:40
>>> rate =float( input(“Enter Rate”))
enter rate: 10
>>> pay = hrs*rate
TypeError: can’t multiply sequence by non-int of type ‘float’
Solution for this:
hrs = float(input(“Enter Hours:”))
rate = float(input(“enter rate”))
pay = hrs*rate
print(‘Pay:’ , pay)

if you are still getting error then check “environment variables”. You need to add python installed folder path at environment variables.
if your python install path is : C:\Programs\Python\Python37-32 then go to control panel, systems–> Advanced system settings –> Advanced tab –> Environment variables –> System Variables –> Path edit –> at variable name enter your python installation path with “;” i.e. “;C:\Programs\Python\Python37-32;” . hit ok.
