Displaying just the capital letters of a string

Question

This sounds simple but how can i display the capital letters of a string like:

string = "Hey There"

Then displays

'HT'

Take a look at [str.isupper](https://docs.python.org/3/library/stdtypes.html#str.isupper). — PM 2Ring, Sep 23 '18 at 12:45

Try this

''.join([word[0] for word in s.split() if word[0].isupper()])

s being the string you want to find the capital letters, you split the string into words and choose those which have a upper case first letter.

In case you want all the capital letters off the string

''.join(c for c in s if c.isupper())

In this we check if every character c is upper case and join all such characters.

Explain your solution. Just giving one liner without explaining is no good except just giving the output. Without explanation, it's hard to make it transferable to other similar problems – Sheldore Sep 23 '18 at 12:21
