How to insert space after every element in a list in Python

Question

I have a list 'decrypted_characters' that looks like this

['mathematician', 'to', 'present', 'a', 'proof', 'of', 'the', 'sensitivity']

I want it to look like a paragraph so I tried

decrypted_word = ''.join(decrypted_characters)

and when I print it looks like

mathematiciantopresentaproofofthesensitivity

How to add spaces after each element so that it looks like sentence? I want it to look like

mathematician to present a proof of the sensitivity

Thanks!

Use join:

In [4]: ' '.join(['mathematician', 'to', 'present', 'a', 'proof', 'of', 'the', 'sensitivity'])

Out[4]: 'mathematician to present a proof of the sensitivity'

What if the list is very long? – Siddharth C Sep 15 '19 at 23:27
You can use the spread operator, decrypted_word = ' '.join([...decrypted_characters]) this will spread your array out, and the above suggestion should work nicely – Sweet Chilly Philly Sep 15 '19 at 23:29

decrypted_characters = ['mathematician', 'to', 'present', 'a', 'proof', 'of', 'the', 'sensitivity']
decrypted_word = ' '.join(decrypted_characters)
print(decrypted_word)

Try this out.
