The following programs demonstrate some Examples of Using Loops in Python.

Like other programming languages, python also has a for loop. The following loop varies the variable x from 0 to 34 and prints x multiplied by 3.

``````for x in range(35):
print(3*x, end=", ")``````

Output

Another example of using for loop is here. The following code prints each element of the list four times.

``````a = ['Sam', 'Joe', 'Luke']

for user_name in a:
print(user_name*4)``````

Output

Similarly, we can use a for loop to print a series. The following code displays a series from 12 to 0 with each term of the series decremented by three.

``````my_nn = 12

while my_nn >= 0:
print(my_nn)
my_nn -= 3``````

Output

The following loop demonstrates the use of break statement. When i becomes greater than 14, the loop terminates.

``````for i in range(20):
if i > 14:
break
print(i)``````

Output

Likewise, the following code demonstrates the use of continue statement. When i becomes equal to 7, the corresponding iteration skips the rest of the statements. Afterward, the loop continues. Hence, the loop all prints all numbers from 0 to 13, except the number 7.

``````for i in range(14):
if i == 7:
continue
print(i)``````

Output
