Loops

Looping is a control flow statement that is used to repeatedly execute a group of statements as long as the confition is satisfied. There different type of *control flow statements” in python. Here’s the most used.

The following table summarizes the main characteristics of each loop:

Loop Type	Description
For-loop	A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string).
While-loop	With the while loop we can execute a set of statements as long as a condition is true.

for-loop

There are multiple ways to use a for-loop. Here’s some examples.

For-loop in-range

# This is a simple loop
for i in range(10):
    print(i)

For-loop with list

# This is a loop with a list
my_list = ["a", "b", "c"]
for i in my_list:
    print(i)

For-loop with list and index

# This is a loop with a list and index
my_list = ["a", "b", "c"]
for i, item in enumerate(my_list):
    print(i, item)

While-loop

The while-loop is used to repeat a block of code as long as the condition is true. Here’s an example.

# This is a while loop
# It will run until the condition is true
i = 0
while (i < 10):
    print(i++)

Break

The break statement is used to exit a loop. Here’s an example.

# This is a while loop
# It will run until the condition is true
# or until the break statement is called
i = 0
while (i < 10):
    i += 1
    print(i)
    if i == 5:
        break
