You have a text and you want to remove punctuations from it. Example:
in: "Hello! It is time to remove punctuations. It is easy, you will see." out: "Hello It is time to remove punctuations It is easy you will see"
Let’s see a Python 3 solution:
>>> import string >>> tr = str.maketrans("", "", string.punctuation) >>> s = "Hello! It is time to remove punctuations. It is easy, you will see." >>> s.translate(tr) 'Hello Its time to remove punctuations Its easy youll see'
You have a string, and you want to replace some characters to some other characters. The first thing that pops into mind is “replace”:
>>> s = "ebbe" >>> s.replace('e', 'a') 'abba'
But what if you need to replace 1s to 0s and 0s to 1s in “100”? The result, in this case, should be “011”.
A straightforward solution would be to use a “temporary variable”, in this case a third kind of character:
>>> s = "100" >>> s.replace('1', 't').replace('0', '1').replace('t', '0') '011'
A more elegant way is to use “translate”:
>>> s = "100" >>> s.translate(str.maketrans('01', '10')) '011'
