Python字符串
#当一句中有单引号的时候,字符串用双引号 print ("Let's go" ) #或者使用转义字符处理字符串中的单引号 print ('Let\'s go') #字符串拼接 x="Hello " y="World!" print (x+y) #str 把值转化为合理的字符串 print (str("10000L")) #repr 创建一个字符串,以合法的形式表示值 print (repr ("100L")) temp=18 print ("The temperature is "+repr (temp)) #单引号和双引号基本没有啥区别 name=input('What is your name:') print ("My name is "+name +'!') #如果一个字符串需要跨多行,使用三个引号代替普通引号或者三个双引号 print ('''This is a very long string. This is a very long string. This is a very long string. This is a very long string. This is a very long string. This is a very long string. This is a very long string.This is a very long string''') print ("""This is a very long string. This is a very long string. This is a very long string. This is a very long string. This is a very long string. This is a very long string. This is a very long string.This is a very long string""") #下面的使用反斜线进行转义 path1='C:\\n0where' print (path1) #原始字符以r开头,原始字符串最后一个字符串不能是反斜线 path2=r'C:\n0where' print (path2) #如果希望原始字符只以一个反斜线结尾,简单方法就是转义 path2=r'C:\n0where''\\' print (path2)
