python中append、extend、和insert的区别

a_list = [x for x in range(1, 11)]

print(a_list)

a_list.append('sdadfewf')  # 将整个字符串放到列表的最后

print(a_list)

# [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 'sdadfewf']

b_list = [x for x in range(1, 11)]

print(b_list)

b_list.extend('sdadfewf')  # 将字符串中的每个元素放到列表的最后

print(b_list)

# [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 's', 'd', 'a', 'd', 'f', 'e', 'w', 'f']

c_list = [x for x in range(1, 11)]

print(c_list)

c_list.insert(3, 'sdadfewf')  # 将整个字符串插入到列表索引为3的位置

print(c_list)

# [1, 2, 3, 'sdadfewf', 4, 5, 6, 7, 8, 9, 10]
