执行多个嵌套for循环的更简单方法

def nested_for_loop(n, loops, current_loop=[]):
    if n == 0:
        # 执行循环体的操作
        print(current_loop)
    else:
        for i in range(loops[n-1]):
            nested_for_loop(n-1, loops, current_loop + [i])

# 示例调用
nested_for_loop(3, [2, 3, 4])

from itertools import product

def nested_for_loop(loops):
    for combination in product(*loops):
        # 执行循环体的操作
        print(combination)

# 示例调用
nested_for_loop([[2, 3, 4], [5, 6, 7], [8, 9, 10]])
