How to output text to the screen
In Python, to output text to the screen, you can use print()functions. This function is a built-in function in Python and is very commonly used. Let's learn how to use it together.
use print()function
print()Functions are used to output content to the terminal (screen). You can put the text you want to output in parentheses as parameters of the function. Here is a simple example:
print("Hello, World!")
In this example, we print()output a string using a function "Hello, World!". After running this line of code, you will see this string in the terminal.
Output multiple content
In addition to outputting a single string, you can also print()output multiple contents at the same time in the function, separated by commas. For example:
name = "Alice"
age = 25
print("My name is", name, "and I am", age, "years old.")
In this example, we output both the string and the variable value. print()The function will automatically separate each content with spaces to make the output more beautiful.
case analysis
Write a Python script and want to output a welcome message to welcome the user. The following code was used:
user_name = "小明"
print("欢迎", user_name, "使用我们的程序！")
Through this code, not only the welcome message is successfully output, but also user_namethe value of the variable is subtly embedded in the output text, making the output more personalized.
Summarize
Using print()functions is a very basic but very useful operation in Python. It allows text and variable values to be output to the screen, adding interactivity and readability to programs.
