if __name__ == '__main__': 
    str1='Hello '
    str2="World !"
    str3=str1+str2 #combine
    str4=str1*2 #double
    str5=str4.replace(" Hello"," World !") #replace string
    print(str1)
    print(str2)
    print(str3)
    print(str4)
    print(str5)
    print "Hello" in str4
    print "!" in str4
    print(len(str4)) #string length
    print(str3.split(" ")) #split String
    print(dir(str1)) # string type character
    pass

執行結果

Hello 
World !
Hello World !
Hello Hello 
Hello World ! 
True
