Capitalize letter with list comprehension

Question

names = ['one', 'two']
print([n[0].upper() for n in names])

I want output like this: One, Two

how can I do this with python?

Should `'oNe'` be `'One'` or `'ONe'`? Because that matters when you use `.title()`. — Austin, Sep 15 '18 at 19:13

>>> names = ['one', 'two']
>>> names = [n.title() for n in names]
>>> names
['One', 'Two']
>>>

If you want it to work with a capital letter in it like oNe will be ONe then:

>>> names = ['oNe', 'twO']
>>> names = [n[0].upper()+n[1:] if n else "" for n in names]
>>> names
['ONe', 'TwO']
>>>

You need to use the method 'capitalize()' of the Python Standard Library.Here is the code :

names = ['one', 'two']
print([n.capitalize() for n in names])

So, you will get this output: ['One', 'Two']
