User input:
# Author :yanpengtao # !/usr/bin/env python # _*_coding:utf-8_*_ username = input("username:") password = input("password:") print(username, password)
The above program asks the user to enter a username and password, then prints the username and password
Formatted output:
The above has learned to format the output string, but many times we need to output digital, floating-point data, so what should we do? First try the following changes
After execution, it was found that an error was reported
When outputting, an error is reported according to the integer output, indicating that the input is not an integer data but a character data (the input data in python is a string type by default), which can also help us detect the data type of the data.

No error will be reported after execution
Here's another way to format the output
