16.Nested Loops
A nested loop is a loop inside another loop.The "inner loop" will be executed completely for each iteration of the "outer loop": we can nest while loops, for loops or the combination. Syntax The syntax for a nested while loop statement in Python programming language is as follows while expression: while expression: statement(s) statement(s) The syntax for a nested for loop statement in Python programming language is as follows for iterating_var in sequence: for iterating_var in sequence: statements(s) statements(s) Note: indentation is very important to identify the code blocks Example: i=1 while i<=3: j=1 while j<=i: print(j,end=' ') # inner ...
