What's the best way to find all possible combinations of a numeric string in Python and compare them with a given string?

问题

我不知道如何解决我的问题。我有一个字符串，像'0.0.0'，我需要找到所有可能的组合，像'0.0.1'，'0.0.2'...... '9.9.9'，然后与另一个字符串比较是否更大或不大。

现在我有这样的代码：

  1. K = 1
  3. res = []
  4. for ele in version_string:
  6.     if ele.isdigit():
  7.         res.append(str(int(ele) + K))
  8.         version_string = res
  9.         version_string = ''.join(version_string)
  10.     else:
  11.         res.append(ele)
  13. print(str(version_string))

输出

  1. 0.0
  2. 1.1
  3. 2.2
  4. 3.3
  5. 4.4
  6. 5.5
  7. 6.6

这段代码只是逐一递增每个数字，但我需要所有的组合。

谢谢

i've no idea how to resolve my problem. i ve a string like '0.0.0' and i need to find all possible combinination, like '0.0.1', '0.0.2'....... '9.9.9' then compare with another string if is bigger or no.
no i've code like this

  1. K = 1
  3.     res = []
  4.     for ele in version_string:
  6.         if ele.isdigit():
  7.             res.append(str(int(ele) + K))
  8.             version_string = res
  9.             version_string = ''.join(version_string)
  10.         else:
  11.             res.append(ele)
  13.     print(str(version_string))

output

  1. 0.0
  2. 1.1
  3. 2.2
  4. 3.3
  5. 4.4
  6. 5.5
  7. 6.6

this code only increment every number by one but i need all combination.

thanks

  1. 如果你想在没有额外模块的帮助下完成这个任务，那么：
  3.     s = '0.0.0'
  4.     
  5.     def combos(s):
  6.         w = s.count('.') + 1
  7.         for x in range(10**w):
  8.             yield '.'.join(f'{x:0{w}}')
  9.     
  10.     def func(s):
  11.         for combo in combos(s):
  12.             print(combo)
  13.     
  14.     func(s)
英文:

If you want to do this without the aid of additional modules then:

  1. s = '0.0.0'
  3. def combos(s):
  4.     w = s.count('.') + 1
  5.     for x in range(10**w):
  6.         yield '.'.join(f'{x:0{w}}')
  8. def func(s):
  9.     for combo in combos(s):
  10.         print(combo)
  12. func(s)

  1. import itertools
  3. for numstr in ('.'.join(map(str, p)) for p in itertools.product(range(10), repeat=3)):
  4.     print(numstr)
