python repeat

# 重复字符串三次
repeated_string = "hello" * 3
print(repeated_string)  # 输出: hellohellohello

# 重复列表两次
repeated_list = [1, 2, 3] * 2
print(repeated_list)  # 输出: [1, 2, 3, 1, 2, 3]

# 重复元组四次
repeated_tuple = (4, 5) * 4
print(repeated_tuple)  # 输出: (4, 5, 4, 5, 4, 5, 4, 5)

original_list = [1, 2, 3]
repeated_list = original_list * 2
original_list[0] = 99
print(repeated_list)  # 输出: [99, 2, 3, 99, 2, 3]

import copy

repeated_list = [copy.deepcopy(item) for item in original_list] * 2
original_list[0] = 99
print(repeated_list)  # 输出: [1, 2, 3, 1, 2, 3]
