.replace() to replace elements in a Pandas DataFrame

[Michio Suginoo]

Hi MRAB,

Sorry, I simply do not understand the intention of your statement.
If .replace() does not do what I want to do: to replace all ' í ' with  'i'
in any form .
Could you advise me other means to do it?

I am still a learner, so I am not knowledgeable. But, I presume, this sort
of needs--to replace parts of string, not an entire string--should be
common.
So, I would presume, there must be some popular way to do it.
If you know, I would appreciate it if you could advise me.

Thanks.
Best
