German Unity Day
From Wikipedia, the free encyclopedia
The Day of German Unity (German: Tag der DeutschenEinheit) is the national day of Germany, celebrated on 3 October as a public holiday. It commemorates the anniversary of German reunification in 1990, when the goal of a united Germany that originated in the middle of the 19th century, was fulfilled again. Therefore, the name addresses neither the re-union nor the union, but the unity of Germany. The Day of German Unity on 3 October has been the German national holiday since 1990, when the reunification was formally completed.

Sample Solution:

Python Code :

import collections
import pprint
file_input = input('File Name: ')
with open(file_input, 'r') as info:
  count = collections.Counter(info.read().upper())
  value = pprint.pformat(count)

Sample Output:

File Name:  abc.txt
Counter({' ': 93,
         'E': 64,
         'N': 45,
         'A': 42,
         'T': 40,
         'I': 36,
         'O': 31,
         'R': 29,
         'H': 25,
         'D': 19,
         'M': 17,
         'Y': 17,
         'L': 15,
         'F': 15,
         'U': 14,
         'C': 13,
         'G': 13,
         'S': 12,
         ',': 7,
         'B': 6,
         'W': 5,
         '9': 5,
         '.': 4,
         'P': 4,
         '1': 3,
         '\n': 2,
         '0': 2,
         '3': 2,
         ':': 1,
         '-': 1,
         'K': 1,
         '(': 1,
         ')': 1,
         'V': 1})

Python: Tips of the Day

Returns the symmetric difference between two lists, after applying the provided function to each list element of both:


def tips_symmetric_difference_by(p, q, fn):
  _p, _q = set(map(fn, p)), set(map(fn, q))
  return [item for item in p if fn(item) not in _q] + [item for item in q if fn(item) not in _p]
from math import floor
print(tips_symmetric_difference_by([4.2, 2.4], [4.6, 6.8],floor))


[2.4, 6.8]
