如何使用Python代码查找关联 [英] How to find associations using Python code

问题描述

我有一个元组：[[G，E]，[B，F]，[G，F]，[G，D]，[D，E]，[H]，[B，E]，[ E，F]，[I]]



您是否有关于如何编写python代码以识别每个字母的其他字母关联的想法。例如，对于E，我们需要找到G，D，B，F因为它们与E相关联。感谢您的帮助。



我有什么尝试过：

I have a tuple: [[G, E], [B, F], [G, F], [G, D], [D, E], [H], [B, E], [E, F], [I]]

Do you have ideas about how to write a python code to identify the association of other letters for each letter. For example, for E, we need to find G, D, B, F because they are associate with E. Appreciate your help.

推荐答案

尝试

Try

l = [['G', 'E'], ['B', 'F'], ['G', 'F'], ['G', 'D'], ['D', 'E'], ['H'], ['B', 'E'], ['E', 'F'], ['I']]
r = []
for sl in l:
  count = sl.count('E')
  if count > 0:
    [r.append(c) for c in sl if c != 'E']
print(r)

顺便说一下，平方括号数据结构是 list s，而不是元组 s。

谢谢你的答案，这有助于找到E的关联，所有其他如何，如G，B，D，I，F等。有没有办法使用哈希表这个？谢谢。

Thank you for the answer, this helps finds the association for E, how about all others, such as G, B, D, I, F, etc. Is there a way to use Hash table for this? Thank you.
