Thus, we can use theglobalkeyword to define a global variable in a Python file for use across the other files. Now, to access the global variable of a file in another file, import the file having the global variable as a module in the other file and directly access any global variable...
Once defining the global variables in python, we can use the same in the whole program. We have no need to define the same again. The below steps show how to use global variables in python are as follows. 1) A global variable in Python has a scope throughout the program, which implie...

As soon as we set a variable equal to a value, weinitializeor create that variable. Once we have done that, we are set to use the variable instead of the value. In Python, variables do not need explicit declaration prior to use like some programming languages; you can start using the ...

If we do not specify this, the function thinks that assignments and changes are made to the local variable itself. Thus, we get this error. Use theglobalkeyword to change aglobal variablevalue from inside a Python function. theGlobalKeyword in Python ...
