It is a sequence of instructions that is repeated until a certain condition is reached to complete a task.
| while loops |
With the while loop
we can execute a set of statements as long as a condition is true.
|
| for loops |
for loop is used for iterating over a sequence (I.E a list, a tuple, a dictionary, a set, or a string).

Sample Programs
| Print sum of 1 to 5 using while Loop |
Output |
sum = 0
i = 1
while i <= 5:
sum = sum + i
i = i+1
print("The sum is", sum)
|
The sum is 15

It iterate over a given sequence. (i.e is either a list / tuple / dictionary / set / string).
