# 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")
