将范围为"3-6"或"3-6,12"的范围或部分数组转换为整数数组,如3,4,5,6,12

# 将范围转换为数组
arr1 = list(range(3, 7))
arr2 = list(range(3, 7)) + [12]

# 将范围或部分数组转换为整数数组
arr1 = []
arr2 = []

for i in range(3, 7):
    arr1.append(i)

for i in range(3, 7):
    arr2.append(i)

arr2.append(12)

# 将范围或部分数组转换为整数数组
arr1 = []
arr2 = []

arr1.extend(range(3, 7))
arr2.extend(range(3, 7))
arr2.append(12)
