Python仅获取1到255之间的变量值

Question

data = """
    abcd1   1
    abcd2   2
    abcd3   3
    abcd4   4
    abcd5   5
    abcd6   6
    abcd7   7
    abcd8   8
    abcd9   9
    .
    .
    .
    abcd256 1
    abcd257 2
    abcd258 3
    abcd259 4
    abcd260 5
    abcd261 6
    abcd262 7
    abcd263 8
    abcd264 9
    """

if abcd1, then  Get  value 1,
if abcd2, then  Get  value 2,...so on

if abcd256, then  Get  value 1,
if abcd257, then  Get  value 2,

条件值必须在 1 到 255 之间

检查数据变量中是否已存在字符串。我使用了下面的代码:

check = set()
for line in data.split("\n"):
    if len(line.split()) > 1:
        line = line.strip()
        check.add(line.split()[0])

if not "abcd264" in check:
            print "Not exist":
            value = 9#Help required to get value here 

else:
    print "Its already exist. Program exit"
    sys.exit()

在其他帖子中建议使用 Pandas，但我需要在不使用 Pandas 的情况下实现

如果你想用纯Python来做，你可以尝试这样做:

data = """
    abcd1   1
    abcd2   2
    abcd3   3
    abcd4   4
    abcd5   5
    abcd6   6
    abcd7   7
    abcd8   8
    abcd9   9
    abcd256 1
    abcd257 2
    abcd258 3
    abcd259 4
    abcd260 5
    abcd261 6
    abcd262 7
    abcd263 8
    abcd264 9
    """

data = data.replace("    ","").replace("   "," ").split("\n")[1:-1]
for d in data:
    number = int(d.split()[0][4:])
    print("For number %d the result is: %d" % (number,number % 255))

输出:

For number 1 the result is: 1
For number 2 the result is: 2
For number 3 the result is: 3
For number 4 the result is: 4
For number 5 the result is: 5
For number 6 the result is: 6
For number 7 the result is: 7
For number 8 the result is: 8
For number 9 the result is: 9
For number 256 the result is: 1
For number 257 the result is: 2
For number 258 the result is: 3
For number 259 the result is: 4
For number 260 the result is: 5
For number 261 the result is: 6
For number 262 the result is: 7
For number 263 the result is: 8
For number 264 the result is: 9
