Python: Find an integer with the given number of even and odd digits
Python Programming Puzzles: Exercise-88 with Solution
Write a Python program to find an integer (n >= 0) with the given number of even and odd digits.
Input: Number of even digits: 2 ,Number of odd digits: 3 Output: 22333 Input: Number of even digits: 4 ,Number of odd digits: 7 Output: 22223333333
Sample Solution:
Python Code:
#License: https://bit.ly/3oLErEI
def test(a,b):
return int(evens*"2"+odds*"3")
evens = 2
odds = 3
print("Number of even digits:",evens,",Number of odd digits:",odds)
print("Integer(>= 0) with the given number of even and odd digits:")
print(test(evens, odds))
evens = 4
odds = 7
print("\nNumber of even digits:",evens,",Number of odd digits:",odds)
print("Integer(>= 0) with the given number of even and odd digits:")
print(test(evens, odds))
Sample Output:
Number of even digits: 2 ,Number of odd digits: 3 Integer(>= 0) with the given number of even and odd digits: 22333 Number of even digits: 4 ,Number of odd digits: 7 Integer(>= 0) with the given number of even and odd digits: 22223333333

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
