Description

It is recommended not to use global statement unless it is really necessary. Global variables are dangerous because they can be simultaneously accessed from multiple sections of a program. This frequently results in bugs. This also make code difficult to read, because they force you to search through multiple functions or even modules just to understand all the different locations where the global variable is used and modified.
