python 数据类型 单引号与双引号

s1 = 'hello'
s2 = "world"
s3 = '''If you not leave me, I will by your side until the life end!'''
s4 = """If you not leave me, I will by your side until the life end!"""
print(s3,type(s3))#单引号字符串类型
print(s4,type(s4))#
# 多行字符串
s5 = 'hello' \
     'world'
print(s5,type(s5))
s6 = 'hello\
world'
print(s6,type(s6))
# 转易：\，可以是有特殊含义的字符失去意义，变成普通字符
s7 = 'I\'ll'
print(s7,type(s7))
s8 = 'hello\\nworld'
print(s8,type(s8))#//与r等效作用
# 原生字符串，中间的任何内容都没有特殊含义
s9 = r'hello\nworld'

print(s9,type(s9))

单引号和双引号无区别
