Upper case first letter of each word in a phrase

Question

Ok, I\'m trying to figure out how to make a inputed phrase such as this in python ....

Self contained underwater breathing apparatus

output

Answer 1

Pythonic Idioms

• Using a generator expression over str.split()
• Optimize the inner loop by moving upper() to one call at outside of the loop.

Implementation:

input = 'Self contained underwater breathing apparatus'
output = ''.join(word[0] for word in input.split()).upper()

Answer 2

def myfunction(string):
    return (''.join(map(str, [s[0] for s in string.upper().split()])))

myfunction("Self contained underwater breathing apparatus")

Returns SCUBA

Answer 3

s = "Self contained underwater breathing apparatus" 
for item in s.split():
    print item[0].upper()

Answer 4

I believe you can get it done this way as well.

def get_first_letters(s):
    return ''.join(map(lambda x:x[0].upper(),s.split()))
