Adding spaces in elements of list(PY)

I have a problem:

I have a list that consists of elements of different lenghts: det_slopes_JKH = ['Superpipe Bolgen','JatzPark','Avalanch Training Center','Bräma schwer']

and i would like to add spaces ' ' to the shorter words, with the purpose of having all the elements of the list with the same lenght.

det_slopes_JKH2 = []
for element in det_slopes_JKH:
     if len(element) < len(element[2]:
         det_slopes_JKH2.append(element + ' ')

Thanks

[x.ljust(len(max(det_slopes_JKH,key=len))) for x in det_slopes_JKH ]

You can try this one liner.

I haven't seen string formatting in the other answers and I happen to like formatting, that said I couldn't resist to show my 0.02 answer

maxlen = max(len(elt) for elt in places)
fmt = "%-"+str(maxlen)+"s"
places = [fmt%elt for elt in places]

You need two things:

  1. Length of biggest string using max = len(max(det_slopes_JKH, key=len))
  2. Append spaces until length is equal to length of biggest string. This can be done using ljust() as i.ljust(max). ljust keeps adding spaces to right of string until string length = max.

This can be done using list comprehension as:

>>> det_slopes_JKH = ['Superpipe Bolgen','JatzPark','Avalanch Training Center','Bräma schwer']
>>> [i.ljust(len(max(det_slopes_JKH, key=len))) for i in det_slopes_JKH]
['Superpipe Bolgen        ', 'JatzPark                ', 'Avalanch Training Center', 'Bräma schwer           ']

Your goal is not very clear but I am assuming you want to have all the strings of the same length.

This adds a space to each string until all are of the same length (the length of the longest string):

def equalize_lengths(l):
    length = len(max(l, key=len))
    return [e.ljust(length) for e in l]

Use builtin max with key=len it will give you maximum length string then use len to get the length and then use string formatting.

>>> max(det_slopes_JKH, key=len)
'Avalanch Training Center'
>>> len(max(det_slopes_JKH, key=len)
24
>>> ['{:24}'.format(elem) for elem in det_slopes_JKH]
['Superpipe Bolgen        ', 'JatzPark                ', 'Avalanch Training Center', 'Br\xc3\xa4ma schwer           ']
>>>

This should do the trick:

det_slopes_JKH = ['Superpipe Bolgen','JatzPark','Avalanch Training Center','Bräma schwer']
max_length  = max(len(elem) for elem in det_slopes_JKH)
det_slopes_JKH2 = [elem + ' '*(max_length - len(elem)) for elem in det_slopes_JKH]
print(det_slopes_JKH2)

Result is:

['Superpipe Bolgen        ', 'JatzPark                ', 'Avalanch Training Center', 'Bräma schwer            ']
