Computers are mostly used to store information and extract information from it. Python is one of the most powerful programming languages. We can use Python to get computers to do most routine processes. This blog is all about how we can write one line for loop in Python.

How Can You write one line for loop in Python?

Method 1: One line for loop

The first solution to write one line for loop in Python is using one line for loop technique. This is the basic one-line technique. Therefore, to learn more about this without spending time, consider the following example:

for num in range(1, 5):

   print(num)

Output

1

2

3

4

Method 2: Use one line with list technique

Let’s look at how to loop one line with a list. Therefore, to learn more about this without spending time, consider the following example:

mylst = ["x", "y", "z"]

for i in mylst:

   print(i)

Output

x

y

z

Method 3: Use if … else statement to list comprehension in Python

Excepting two methods mentioned above, there is another solution for you to write one line for loop in Python. It is using if … else statement to list comprehension in Python.

List comprehension with an if/else statement is used to filter elements from an existing list to build a new list or to apply operations to some particular elements of an existing list to create a new list. The following examples show how to use Python’s one-line for loop to implement list comprehension by using the if statement and the if…else statement. If an odd number is present, the example code below adds the components to the new list; otherwise, it removes them.

mylist = [1,4,5,8,9,11,13,12]

newlist = [x for x in mylist if x%2 == 1]
print(newlist)

Output

[1, 5, 9, 11, 13]
