Guibs 的 Python学习_字符串

# 字符串# Python 中, 用引号括起来的都是字符串. 引号可以是单引号, 也可以是双引号"This is a string"'This is also a string'
# 因而可以在字符串中包含 " 或 ''I told myself, "you are Gubis"'"The name 'Guibs' is my nickname"
# 首字母大写指定字符串# [.title()]name = 'Macbook pro'print(name.title())
# 全部大写指定字符串
# [.upper()]print(name.upper())
# 全部小写字符串
# [.lower()]print(name.lower())
# 合并(拼接)字符串
# [使用 + 拼接字符串]first_name = "guibs"last_name = 'g'full_name = first_name + " " + last_name
print(full_name)

hello_message = "Hello, " + full_name.title() + "!"print(hello_message)
# 制表符# [\t]print("Python")
print("\tPython")
# 换行符
# [\n]print("123")
print("1\n2\n3")
# 删除字符串空白# [.rstrip() 删除字符串末尾多余空白]
print("删除字符串 Swift and Python 末尾多余空白")
favorite_language = " Swift and Python "print(favorite_language + " are my favorite languages")
print(favorite_language.rstrip() + " are my favorite languages" + "\n")
# [.lstrip() 删除字符串开头多余空白]
print("删除字符串 Swift and Python 开头多余空白")
print(favorite_language + " are my favorite languages")
print(favorite_language.lstrip() + " are my favorite languages" + "\n")
# [.strip() 删除字符串头尾多余空白]print("删除字符串 Swift and Python 头尾多余空白")
print(favorite_language + " are my favorite languages")
print(favorite_language.strip() + " are my favorite languages" + "\n")
# 正确使用引号
# 保留 "" 显示
print('I told myself, "you are Gubis"')
# 保留 '' 显示
print("The name 'Guibs' is my nickname")
