What are input and output in python? (detailed examples)

For those who are exposed to the python programming language for the first time, when they first started learning python programming, they had little understanding of the input and output in python. In this article In this article, we will learn about python input and output related knowledge.

Output

Use print() to add a string in brackets to output the specified text to the screen. For example, to output 'hello, world', the code is as follows:

>>> print('hello, world')

The print() function can also accept multiple strings, separated by commas ",", and they can be connected into a string for output:

>>> print('The quick brown fox', 'jumps over', 'the lazy dog')
The quick brown fox jumps over the lazy dog

print() will print each string in turn. When it encounters a comma "," it will output a space. Therefore, the output string is spelled out like this:

print() can also print integers, or calculation results:

>>> print(300)
300
>>> print(100 + 200)
300

Enter

Now, you can use print() Output the results you want. But what if you want the user to enter some characters from the computer? Python provides an input() that allows users to enter a string and store it in a variable. For example, enter the user's name:

>>> name = input()
Michael

When you enter name = input() and press Enter, the Python interactive command line is waiting for your input. At this time, you can enter any characters and press Enter to complete the input.

After the input is completed, there will be no prompts, and the Python interactive command line returns to the >>> state. So where did the content we just entered go? The answer is stored in the name variable. You can directly enter name to view the variable content:

>>> name'Michael

In short, any computer program is designed to perform a specific task. With input, the user can tell the computer the information required by the program. With output, after the program is run Only then can the user be told the results of the task.

The input is Input and the output is Output. Therefore, we call input and output collectively Input/Output, or abbreviated as IO.

Input() and print() are the most basic input and output under the command line. However, users can also complete input and output through other more advanced graphical interfaces, such as a text on a web page. Enter your name in the box and click "OK" to see the output information on the web page

The above is all the content described in this article. This article mainly introduces Input and output in python related knowledge, I hope you can use the information to understand the above content. I hope what I have described in this article will be helpful to you and make it easier for you to learn python.
