嵌套的foreach增加两个索引/检查日期是否在2个数组之间

array1 = [1, 2, 3]
array2 = ['a', 'b', 'c']

for i, num in enumerate(array1):
    for j, letter in enumerate(array2):
        print("Index in array1:", i)
        print("Index in array2:", j)
        print("Value in array1:", num)
        print("Value in array2:", letter)

Index in array1: 0
Index in array2: 0
Value in array1: 1
Value in array2: a
Index in array1: 0
Index in array2: 1
Value in array1: 1
Value in array2: b
Index in array1: 0
Index in array2: 2
Value in array1: 1
Value in array2: c
Index in array1: 1
Index in array2: 0
Value in array1: 2
Value in array2: a
Index in array1: 1
Index in array2: 1
Value in array1: 2
Value in array2: b
Index in array1: 1
Index in array2: 2
Value in array1: 2
Value in array2: c
Index in array1: 2
Index in array2: 0
Value in array1: 3
Value in array2: a
Index in array1: 2
Index in array2: 1
Value in array1: 3
Value in array2: b
Index in array1: 2
Index in array2: 2
Value in array1: 3
Value in array2: c

import datetime

date1 = datetime.date(2022, 1, 1)
date2 = datetime.date(2022, 12, 31)
check_date = datetime.date(2022, 6, 15)

if date1 <= check_date <= date2:
    print("The date is between date1 and date2.")
else:
    print("The date is not between date1 and date2.")

The date is between date1 and date2.
