列表和字符串的相互转换

xm = ['zhang3','li4','wang5','zhao6']
a = ','.join(xm)#用逗号连接列表里的内容

a=' '.join(xm)#用空格连接列表里的内容

xm2 = ''
for i in xm:
	xm2 = xm2 + i +' '

xm2 = ' '.join([str(i) for i in xm]) 



a = 'zhang3 li4 wang5 zhao6'
print(a.split(' '))#按照空格来分开    ['zhang3', 'li4', 'wang5', 'zhao6']
print(a.split('，'))#按照逗号来分开    'zhang3，li4，wang5，zhao6'
