Pythonic way to insert every 2 elements in a string
I'll be happy if someone can help with python code)) How can I put the space into a string for example,
If there is the string 'akhfkahgdsds'
I would like to turn it into 'ak hf ka hg ds ds'
>>> s = 'akhfkahgdsds'
>>> range(0, len(s), 2) # gives you the start indexes of your substrings
[0, 2, 4, 6, 8, 10]
>>> [s[i:i+2] for i in range(0, len(s), 2)] # gives you the substrings
['ak', 'hf', 'ka', 'hg', 'ds', 'ds']
>>> ' '.join(s[i:i+2] for i in range(0, len(s), 2)) # join the substrings with spaces between them
'ak hf ka hg ds ds'
def isection(itr, size):
while itr:
yield itr[:size]
itr = itr[size:]
' '.join(isection('akhfkahgdsds', 2))
I don't really think this is the way to go here, but I think this answer is kind of fun anyway. If the length of the string is always even, you can play neat tricks with iter -- if it's odd, the last character will be truncated:
s = '11223344'
i_s = iter(s)
' '.join(x+next(i_s) for x in i_s)
Of course, you can always pad it:
i_s = iter(s+len(s)%2*' ')
you can try this simple code:
try:
for i in range(0,len(s)+1,2):
print s[i]+s[i+1],
except IndexError:
pass
