'''l=10#global
def fun1():
    #l=5#local
    m=8#local
    #it through error beacuse not have permision if it change so take global keyword
    global l
    l=l+45
    print(l)
fun1()
'''
x=90
def deep():
    x=20
    def rohan():
        global x
        x = 88
    print("before calling rohan()",x)
    rohan()
    print("after calling rohan()",x)

deep()
print(x)

Interpretation vs Compilation

  What is Interpreter? This language processor converts a HLL(High Level Language) program into machine language by converting and executing it line by line. If there is any error in any line, it reports it at the same time and program execution cannot resume until the error is rectified. Interpreter must always be present in the memory every time the program is executed as every time the program is run, it is first interpreted and then executed. For error debugging, interpreter is very much useful as it reports the error(s) at the same time. But once errors are removed, unnecessary usage of memory takes place as it has to be present in the memory always.   What is Compiler? It also converts the HLL program into machine language but the conversion manner is different. It converts the entire HLL program in one go, and reports all the errors of the program along with the line numbers. After all the errors are removed, the program is recompiled, and after that the compiler is not...
