Python: Finding and Pointing to the Midpoint of a string

I just started learning Python (as my first language, so I know next to nothing) and have come across this problem.

Find the midpoint of a word, and poin开发者_StackOverflow社区t to it using a caret "^".

Example,

Computer
   ^

Thanks for any tips anyone could give me.


Use len, which finds the length of the object.

>>> x = "Computer"
>>> x[len(x)/2 - 1]
'p'

-

# a.py
x = "Computer"
print x
print (" " * (len(x)/2 - 1)) + "^"

# % python a.py
Computer
   ^


text='Computer'
print(text)
print('{0:^{1}}'.format('^',len(text)))
  • {0:...} tells format to replace replace itself with the first argument, '^'.
  • {1} gets replaced by the second argument, len(text).
  • ^{1} tells format to center the text, and make the total width equal to len(text).

So the docs for the full specs on format.


The mid point depends on odd or even length of a string. So, if it is an odd length the middle will be exactly len/2+1 if it is an even length, you should decide what is the middle for you (len/2 or len/2+1)

x="Computer"

if len(x)%2: return x[len(x)/2+1]

else: return x[len(x)/2]


I like this format better because it's simple. It just uses the round() function. But this is only to find the midpoint and not to execute the ^, but I assume that should be self-explanatory.

my_str2 = "computer"
output = round(len(my_str2)/2)
print(my_str2[output])
0
