except first item in list - python

I have string:

n = 'my fancy extension'

with 

  ''.join([ x.capitalize() for x in n.split() ])

I get MyFancyExtension, but I need myFancyExtension.

How do I avoid capitalizing the first item in list, or not capitalizing at all if one word only specified?

n = 'my fancy extension'

n = n.title()
n = n.replace(" ", "")
n = n[0].lower() + n[1:]

print(n)

so, there is nothing in python so I could say ''.join([ x.capitalize() for x in l --if x not first elmnt-- ]), part between -- being some index test?

Actually you can use Python's ternary to achieve such an effect:

x if Condition else y

Or, in this case,

x.capitalize() if Condition else x.lower()

For example:

>>> def camel(my_string):
...     my_list = my_string.split()
...     return ''.join([x.lower() if x is my_list[0] else x.capitalize() for x in my_list])
>>> camel("lovely to be here")
'lovelyToBeHere'

Where 'x' is a string piece, 'condition' is if x is my_list[0], and the two options are of course x.lower() and x.capitalize().

Also kind of nice because if you goof up the first part it will lowercase it for you :)

>>> camel("WHat is the problem")
'whatIsTheProblem'
>>>

In most languages it's written as if Condition x else y order, instead of x if Condition else y so a lot of Python folk shy away from it, but personally I think Python's ternary is cool.

Not a fan of dense one-liners, but:

>>> words = "my fancy extension"
>>> ''.join([x.capitalize() if i else x for (i, x) in enumerate(words.split())])
'myFancyExtension'

>>> n = 'my fancy extension'
>>> array = n.split()
>>> array[0] + ''.join(map(str.capitalize, array[1:]))
'myFancyExtension'

l = n.split()
if len(l)>1:
  print l[0] + ''.join([ x.capitalize() for x in l[1:] ])
else:
  print l[0]

or

import re
print re.sub(" ([a-z])", lambda s: s.group(1).upper(), n)

In python 3 you can do:

n = 'my fancy extension'

first,*rest = n.split()

''.join([first] + [x.capitalize() for x in rest])
Out[10]: 'myFancyExtension'

python 2 doesn't have the fancy extended tuple unpacking syntax, so you'd need an extra step (oh no!):

spl = n.split()

first,rest = spl[0],spl[1:]
