Find number of times every day occurs in a Year in Python

PythonServer Side ProgrammingProgramming

When it is required to find the number of times every day of the week occurs in a year, a list is defined, and it is iterated over, and is count is incremented respectively.

Below is a demonstration of the same −

Example

 Live Demo

import math
def num_of_occurrence( n, firstday):

   my_days = [ "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday","Sunday" ]

   my_count= [4 for i in range(0,7)]

   my_position = -1
   for i in range(0,7):
      if (first_day == my_days[i]):
         my_position = i
         break

   inc = n - 28

   for i in range( my_position, my_position + inc):
      if (i > 6):
         my_count[i % 7] = 5
      else:
         my_count[i] = 5

   for i in range(0,7):
      print (my_days[i] , " " , my_count[i])

num = 31
first_day = "Thursday"
num_of_occurrence(num, first_day)

Output

Monday 4
Tuesday 4
Wednesday 4
Thursday 5
Friday 5
Saturday 5
Sunday 4

Explanation

  • The required packages are imported.

  • A method named ‘num_of_occurence’ is defined that takes a number and a day of week as parameter.

  • A list with number of days of week is defined.

  • Another list with numbers in the range of 0 and 7 is defined.

  • The range is iterated over, and if the day passed as parameter matches a day from the list, its position is set.

  • Another iteration is used and the count of every day of the week is incremented depending on the day passed as first day to the method.

  • The method is called by passing the respective parameters.

  • The output is displayed on the console.
