How to use escape characters in Python?

In Python, escape characters are represented by a backslash (\). Here are some common escape characters and their uses: 1. \n: newline character, used to create a new line in a string. 2. \t: tab character, used to create a horizontal tab in a string. 3. \’: single quote, used to insert a single quote in a string. 4. \”: double quote, used to insert a double quote in a string. 5. \\\: backslash, used to insert a backslash in a string. 6. \r: carriage return, used to move the cursor to the beginning of the current line. 7. \b: backspace character, used to move the cursor back one position. Here are some examples:

# 换行符
print("Hello\nWorld")
# 输出：
# Hello
# World
# 制表符
print("Hello\tWorld")
# 输出：
# Hello    World
# 插入单引号
print('I\'m a student')
# 输出：
# I'm a student
# 插入双引号
print("He said, \"Hello!\"")
# 输出：
# He said, "Hello!"
# 插入反斜杠
print("C:\\Users\\Username")
# 输出：
# C:\Users\Username
# 回车符
print("Hello\rWorld")
# 输出：
# World
# 退格符
print("Hello\bWorld")
# 输出：
# HellWorld

It’s important to note that if a string starts with r or R, the backslash will be treated as a regular character, not an escape character. For example:

print(r"C:\Users\Username")
# 输出：
# C:\Users\Username

This will print the original string without interpreting escape characters.
