Python 中字符串修饰符详解

path = r'C:\new_folder\test.txt'  # 原始字符串

name = "Alice"
age = 30
message = f'{name} is {age} years old.'  # 格式化字符串

# 在 Python 3 中：
text = u'Hello, world!'  # Unicode 字符串
# 在 Python 2 中：
text = u'Hello, world!'  # Unicode 字符串

data = b'Hello, world!'  # 字节字符串

multiline_str = """This is a
multiline string that spans
multiple lines."""

path = r'C:\new_folder\test.txt'
name = "Alice"
message = fr'{name}\'s file is located at {path}'
print(message)
# Output: Alice's file is located at C:\new_folder\test.txt

# 使用原始字符串
raw_path = r'C:\Users\Example\Documents\file.txt'
print(raw_path)
# 使用格式化字符串
name = "John"
age = 28
greeting = f'Hello, {name}. You are {age} years old.'
print(greeting)
# 使用 Unicode 字符串
unicode_str = u'こんにちは世界'  # 这在 Python 3 中默认就是 Unicode
print(unicode_str)
# 使用字节字符串
byte_str = b'This is a byte string'
print(byte_str)
# 使用多行字符串
multiline_str = """This is a string
that spans multiple
lines."""
print(multiline_str)
# 组合使用原始和格式化字符串
file_path = r'C:\Users\Example\Documents'
filename = "file.txt"
full_path = fr'{file_path}\{filename}'
print(full_path)
