Python List Comprehension with Examples | Live Practice
In this tutorial, you will learn about python List Comprehension with Examples, You can use this List Comprehension for Data Science and machine learning developments.
Def : It’s a process of creating new lists by using old lists with condition statements
Syntax : [ expression for loop if conditionals]
List Comprehension Advantages :
- Less Code – single line statement.
- Fast code execution when compare to function and map functions
- Special uses cases in machine learning and data science projects
#python example programs on list comprehension
#Print odd and even numbers using list comprehensive method
list = [1,2,3,4,5,6,7,8,9,10]
even_numbers = [i for i in range(10) if(i%2==0) ]
print(even_numbers)
odd_numbers = [i for i in range(10) if(i%2!=0) ]
print(odd_numbers)
Output:
[0, 2, 4, 6, 8] [1, 3, 5, 7, 9]
#multiplication using list comprehension
multiplication = [5*i for i in list ]
print(multiplication)
Output:
[5, 10, 15, 20, 25, 30, 35, 40, 45, 50]
#functions in list comprehension
list = ["Hello Python", '3','Hi','5']
is_digit = [i for i in list if i.isdigit() ]
print(is_digit)
Output:
['3', '5']
list = ["Hello Python"] lower = [i.lower() for i in list] print(lower)
Output:
['hello python']
To Uppercase :
list = ["Hello Python"]
upper = [i.upper() for i in list]
print(upper)
Output:
['HELLO PYTHON']
