Regex to find words starting with capital letters not at beginning of sentence

Question

I've managed to find the words beginning with capital Letters but can't figure out a regex to filter out the ones starting at the beginning of the sentence.

Each sentence ends with a full stop and a space.

• Test_string = This is a Test sentence. The sentence is Supposed to Ignore the Words at the beginning of the Sentence. This is a Test sentence. The sentence is Supposed to Ignore the Words at the beginning of the Sentence.

• Desired output = ['Test', 'Supposed', 'Ignore', 'Words', 'Sentence']

I'm coding in Python. Will be glad if someone can help me out with the regex :)

Answer 1

You may use the following expression:

(?<!^)(?<!\. )[A-Z][a-z]+

import re
mystr="This is a Test sentence. The sentence is Supposed to Ignore the Words at the beginning of the Sentence."

print(re.findall(r'(?<!^)(?<!\. )[A-Z][a-z]+',mystr))

Prints:

['Test', 'Supposed', 'Ignore', 'Words', 'Sentence']

Answer 2

A very basic option. See here for an explanation.

[^.]\s([A-Z]\w+)

---

import re
s = 'This is a Test sentence. The sentence is Supposed to Ignore the Words at the beginning of the Sentence, And others.'
re.findall(r'[^.]\s([A-Z]\w+)', s)

output

['Test', 'Supposed', 'Ignore', 'Words', 'Sentence', 'And']
