将字典转换成变量， 字符串与列表相互转换

Posted 2020-09-23 何必从头

将字典转换成变量：
>>> locals().update({‘a‘:1,‘b‘:2})
>>> a
1
>>> b
2

字符串与列表相互转换
    str >>>list 
        str1 = "12345"  
        list1 = list(str1)  
        print list1  
          
        str2 = "123 sjhid dhi"  
        list2 = str2.split() #or list2 = str2.split(" ")  
        print list2  
          
        str3 = "www.google.com"  
        list3 = str3.split(".")  
        print list3  
    list >>>str
        str4 = "".join(list3)  
        print str4  
        str5 = ".".join(list3)  
        print str5  
        str6 = " ".join(list3)  
        print str6
