#Python3.0中所有字符串都是unicode
name = raw_input("input your name:")#input 用户需要输入"name"
print("hello,"+name)
raw_input("Press <enter>")
print(repr("HelloWorld!"))
print(str("HelloWorld!"))
print(repr("100000000L"))
print(str("100000000L"))
print(repr("100000000L")+repr("hello"))
print("hello,"+"erveryone---"\
+"-----niub")#\可以连接两行
print("c\nowhere") #\n为换行，所以不会输出想象的情况。
print("c\\nowhere") #这样可以正常输出
print(r"c\nowhere") #r""可以避免输入大量\\
#find查找字符串索引，没找到返回-1
str = "123xsdasd"
print(str.find("xs"))
print(str.find("xs",10,24))#提供起始点和结束点
#join
seq = ["1","2","3","4","5"]
seq2 = "+".join(seq)
print(seq)
print(seq2)
#序列转化为字符串
str = "".join(seq)
print(str)
dirs = ["","usr","bin","env"]
print("/".join(dirs))
print("C:"+"\\".join(dirs))
#lower,upper大小写转化 title或capwords首字母大写
print("sdasdDASAS".lower())
print("sdasdDASAS".upper())
print("it's niu b".title())
import string
print(string.capwords("it's niu b"))
#replace替换
print("123123123123123".replace("1","4"))
#split分隔
print("1+2+3+4+5".split("+"))
#strip 去除两侧空格
print(" sd ".strip())
运行结果：
