How to use the print statement to output content to the console in Python 2.x

In the Python 2.x version, we can use the print statement to output content to the console. The following will introduce in detail how to use the print statement and some precautions.

Basic usage

print The basic usage of the statement is very simple. We just need to add the content that needs to be output after print, and then put it in quotation marks (single or double quotation marks). For example:

print "Hello, world!"

The above code will output "Hello, world!" to the console.

Output variables

We can also use the print statement to output the value of a variable. Just use a comma to separate the print statement from the variable name. For example:

name = "Alice"
age = 23
print "My name is", name, "and I am", age, "years old."

The above code will output "My name is Alice and I am 23 years old." to the console.

Output multiple contents

If we want to output multiple contents on one line, we can use the print statement to enter each content separately and separate them with commas. For example:

print "This", "is", "a", "test."

The above code will output "This is a test." to the console.

Control output format

We can also use special characters to control the output format. The following are some commonly used characters:

• `
  `: newline character
• : tab character
• : Backspace character
• ``: Carriage return character
• \: Backslash
• ": Double quotes
• ': Single quotes

Here is an example:

print "This is a test.
"
print "This    is    a    test."

The above code will output:

This is a test.

This    is    a    test.

Print formatted string

We can also use the % operator to format the string output. Where we need to insert variable values, we use the placeholder %s (representing a string), %d (representing an integer), or %f (representing a floating point number). Then use it in the string after the print statement % operator and put the required variables in parentheses.

Here is an example:

name = "Bob"
age = 30
print "My name is %s and I am %d years old." % (name, age)

The above code will output "My name is Bob and I am 30 years old." to the console.
