Python valueerror:invalid literal for int. () with base 10 practical workaround

Copy the Code code as follows:

TotalCount = ' totalpage = Int (totalcount)/20
Valueerror:invalid literal for int. () with base 10 error

The same error on the web was suggested with round (float ("1.0″)"), but it could not solve my problem, round ("1.0″") is used to solve the floating-point number conversion to shaping numbers,
And I this is because the original string into the shape after the division, although a period of time may not error, but a long time will prompt (in fact, is a warning, but will force the termination of your program), the correct solution is as follows:
Copy the Code code as follows:

Remove non-numeric characters from the string. Pro-Test available
