This article will explain in detail how python uses the map () function. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Map ()

Map () is a built-in Python function that applies a function to a sequence of elements, such as a list or dictionary. It is probably the easiest and most readable way to manipulate data.

The following example is designed to find the square of the number in the list. First, you must be clear about the function you are using. Next, the author shows and compares the methods that use map () and those without map (), that is, python and non-python.

Nums = [1, 2, 3, 4, 5] # this function will calculate square def square_num (x): return xanthates 2 # non-pythonic approach squares = [] for num in nums: squares.append (square_num (num)) print ('Non-Pythonic Approach:', squares) # pythonic approach x = map (square_num, nums) print ('Pythonic Approach:', list (x))

The output is essentially the same, but the python method is significantly more concise and the process does not require a loop.

This is the end of the article on "how python uses the map () function". I hope the above content can be of some help to you, so that you can learn more knowledge. if you think the article is good, please share it out for more people to see.
