Question

我创建了一组字符串编号，以便与另一组字符串编号匹配

这是漫长而艰难的方式，是否有更好或更短的方式，我可以轻松地扩展此列表，再说500多

此代码的第二部分在这里---（xyz） - 字符串数字1到100000，基本上是文件名的一部分

   if str(a) == xyz:
       print (a)
    elif str(b) == xyz:
        print (b)
    elif str(c) == xyz:

这继续我和elif elif elif直到92次，然后我停止了:)

Answer 1

对第一部分使用for - 循环：

for a in range(i, i + 93):
    print 'grabing file', a

，第二部分是一个简单的if：

if i <= int(xyz) <= i + 92:
    print int(xyz)

Answer 2

请参阅python的control flow结构，尤其是for循环。

＃1

i = 100      # Arbitrary Value
limit = 100  # Arbitrary Value
xyz = '199'  # Arbitrary Value

for num in range(i, i+limit):
    print 'grabing file',(num)

＃2

if num == int(xyz):
    print num  # Do something.

Answer 3

我会创建一本字典。键可以只是数字：

i = 3 #or some other number
d = {}
for x in range(0,92):  #you can also change the range to 500 etc
  d[x]=i
  i +=1

在这种情况下，这会创建一个字典或一对系统。一把钥匙和一个价值。

要打印其值与Key匹配的xyz，您可以使用以下内容：

[m for m, y in d.iteritems() if str(y) == xyz]

这部分基本上贯穿你的值，寻找匹配并打印Key

python - 有没有更好的方式来编写这个，更短，更容易添加更多
