一、list转字符串

命令:''.join(list)
其中,引号中是字符之间的分割符,如“,”,“;”,“\t”等等
如:
list = [1, 2, 3, 4, 5]
''.join(list) 结果即为:12345
','.join(list) 结果即为:1,2,3,4,5

二、字符串转list

print list('12345')
输出: ['1', '2', '3', '4', '5']
print list(map(int, '12345'))
输出: [1, 2, 3, 4, 5]

str2 = "123 sjhid dhi"
list2 = str2.split() #or list2 = str2.split(" ")
print list2
['123', 'sjhid', 'dhi']

str3 = "www.google.com"
list3 = str3.split(".")
print list3
['www', 'google', 'com']
