print(v)

extend 扩展原列表

user_list = ['xmzncc','asd','fcc']
user_list.extend(['qwe'])
print(user_list)

index 查找元素索引

user_list = ['xmzncc','asd','fcc']
v = user_list.index('xmznc')
print(v)

pop 删除索引，获取元素

user_list = ['xmzncc','asd','fcc']
v = user_list.pop(0)
print(v)
print(user_list)

remove 删除元素

user_list = ['xmzncc','asd','fcc']
v = user_list.remove('xmzncc')
print(v)
