When creating a for loop, it appears that python adds spaces.
menuItems = ['apple', 'banana', 'car', 'thing', 'whatever', 'burrito']
menuNum = 1
for menuItem in menuItems:
print menuNum,'. ',menuItem
menuNum = menuNum + 1
returns this
1 . apple
2 . banana
3 . car
etc...
Any idea on how I can simply get this without the spacing?
eg.
1. apple
2. banana
3. car
Use string formatting. print in Python 2 puts a space for each comma used to separate the items.
>>> data = ['apple', 'banana', 'car', 'thing', 'whatever', 'burrito']
for i, item in enumerate(data, 1):
print '{}. {}'.format(i, item)
...
1. apple
2. banana
3. car
4. thing
5. whatever
6. burrito
And use enumerate if you want index as well items.
Use one of Python's formatting capabilities.
print "{} . {}".format(menuNum, menuItem) # 2.7+ or 3.x
print "%d . %s" % (menuNum, menuItem)
The print expression in Python 2 puts spaces between the items on a single line. To avoid this, create a single string first that looks like you want to output to appear:
# string formatting
for menuItem in menuItems:
print '{0}. {1}'.format(menuNum, menuItem)
Or else, use the Python3 print function, which has more options available.
# print function
from __future__ import print_function
for menuItem in menuItems:
print(menuNum, '. ', menuItem, sep='')
Just use:
from __future__ import print_function
print(menuNum, '. ', menuItem, sep='')
You could also use string formatting:
print '{0}. {1}'.format(menuNum, menuItem)
You have a space after the ". " when using a comma and printing, a space is inserted for you. Altough I use python 3.3, as far as I'm aware, using '+' should still work. Unless I'm missing something; the following would work fine.
print menuNum + '.' + menuItem
forloop aside from yourprintstatement being inside one? In other words, why do you think this problem is being caused byfor?
