如何在Python中获取1-100，110-130之间的数字

Question

如何在Python中获取1到100之间的数字？这个场景是用户会输入一个字符，比如1-100或者110-120，意思是我想要这样的格式：[1,2,3,4,5...100]和[110,111,112,113...120]。那么在Python中该怎么做呢？

Answer 1

使用 range()：

low = int(raw_input('Enter the bottom number: '))
high = int(raw_input('Enter the top number: '))
print range(low, high+1)

这段代码运行的结果是：

Enter the bottom number: 110
Enter the top number: 120
[110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120]

Enter the bottom number: -50
Enter the top number: -10
[-50, -49, -48, -47, -46, -45, -44, -43, -42, -41, -40, -39, -38, -37, -36, -35, -34, -33, -32, -31, -30, -29, -28, -27, -26, -25, -24, -23, -22, -21, -20, -19, -18, -17, -16, -15, -14, -13, -12, -11, -10]

编辑：

或者，如果用户输入的是一个字符串：

low, high = raw_input('Enter the range separated by a hyphen (10-20): ').split('-')
print range(int(low), int(high)+1)

这段代码运行的结果是：

Enter the range separated by a hyphen (10-20): 10-20
[10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20]

---

Enter the range separated by a hyphen (10-20): 100-150
[100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, 144, 145, 146, 147, 148, 149, 150]

Answer 2

如果你想传递一个像 1-100,110-120,140-15 这样的字符串，或者像 1-100 这样的字符串，可以使用：

def separator(string):
    if ',' in string:
        sep_strings = string.split(',')
        limits = [i.split('-') for i in sep_strings]
    else:
        limits = [string.split('-')]
    return limits

def ranger(string):
    results = []
    ranges = separator(string)
    for element in ranges:
        start = int(element[0])
        stop = int(element[1]) + 1
        results += [range(start,stop)]
    return results

print ranger(raw_input("Enter a range: "))

输出

(如果输入是 1-100,110-120,140-15)：

[[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100],
[110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120], 
[140, 141, 142, 143, 144, 145, 146, 147, 148, 149, 150]]
