The elif Statement :

The elif keyword is pythons way of saying "if the previous conditions were not true, then try this condition".

Syntax :

if expression1: statement(s)
elif expression2: statement(s)
elif expression3: statement(s)
else: statement(s)

Nested if-elif-else Statement :

C++ nested if Statements | C# nested if Statements - There may be a situation when you want to check for another condition after a condition resolves to true. In such a situation, you can use the nested construct.

Example :

a = 200 b = 20 c = 200 if (a == c): if (a > 200): print("a is small [nested - 1]") elif (a == 200): print("a is equal [nested - 1]") if( a != b ) : print("a is not equal to b [nested - 2]") elif(a == b) : print("a is equal to b [[nested - 2]]") else : print("another expression [nested - 2]") else: print("a is not equal [nested - 1]") elif (a == b): print("a and b are equal") else: print("a is not equal") input()
