Python map: Exercise-13 with Solution

Write a Python program to count the same pair in two given lists. use map() function.

Sample Solution:

Python Code:

from operator import eq
def count_same_pair(nums1, nums2):
    result = sum(map(eq, nums1, nums2))
    return result

nums1 = [1,2,3,4,5,6,7,8]
nums2 = [2,2,3,1,2,6,7,9]
print("Original lists:")
print(nums1)
print(nums2)
print("\nNumber of same pair of the said two given lists:")
print(count_same_pair(nums1, nums2))

Sample Output:

Original lists:
[1, 2, 3, 4, 5, 6, 7, 8]
[2, 2, 3, 1, 2, 6, 7, 9]

Number of same pair of the said two given lists:
4

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")
