Python For Loop List a for loop can be used to iterate over the elements of a list. Here is the basic syntax for a for loop that iterates over a list:<\/p>\n\n\n

my_list = [1, 2, 3, 4, 5]\nfor element in my_list:\n    # code to be executed for each element\n<\/code><\/pre>\n\n\n\n
In this loop, the element<\/code> the variable takes on the value of each element in the my_list list, one at a time, and the code inside the loop is executed for each iteration.<\/p>\n\n\n\n
Python For Loop List Example in Details.<\/h2>\n\n\n\n
 For example, if we want to print each element in a list, we can use a for loop like this  Python For Loop List:<\/p>\n\n\n\n
my_list = ['apple', 'banana', 'cherry']\nfor fruit in my_list:\n    print(fruit)\n<\/code><\/pre>\n\n\n\n
Output:<\/strong><\/p>\n\n\n\n
apple\nbanana\ncherry\n<\/code><\/pre>\n\n\n\n
In this loop, the fruit<\/code> the variable takes on the value of each element in the my_list list, one at a time, and the print() function is called for each iteration to print the value of fruit<\/code>.<\/p>\n\n\n\n
We can also modify the elements of a list using a For loop<\/a>. For example, if we want to square each element in a list and replace the original elements with their squares, we can use a for loop like this:<\/p>\n\n\n\n
my_list = [1, 2, 3, 4, 5]\nfor i in range(len(my_list)):\n    my_list[i] = my_list[i] ** 2\nprint(my_list)\n<\/code><\/pre>\n\n\n\n
Output:<\/strong><\/p>\n\n\n\n
[1, 4, 9, 16, 25]\n<\/code><\/pre>\n\n\n\n
In this loop, the range()<\/code> function is used to generate a sequence of indices for the elements of the my_list<\/code> list. The i<\/code> variable takes on the value of each index in the sequence, one at a time, and the my_list[i] = my_list[i] ** 2<\/code> statement is executed for each iteration to square the current element and replace it with its square.<\/p>\n\n\n\n
Note that you can also use list comprehension to achieve the same result in a more concise way:<\/p>\n\n\n\n
my_list = [1, 2, 3, 4, 5]\nmy_list = [x**2 for x in my_list]\nprint(my_list)\n<\/code><\/pre>\n\n\n\n
Output:<\/strong><\/p>\n\n\n\n
[1, 4, 9, 16, 25]\n<\/code><\/pre>\n\n\n\n
This code creates a new list using a list comprehension that iterates over the elements of the original my_list<\/code> and squares each element, producing a new list with the squared values. The original my_list<\/code> is left unchanged.<\/p>\n\n\n\n
