Python: Calculate the time runs of a program

Python Basic: Exercise-133 with Solution

Write a Python program to calculate the time runs (difference between start and current time)of a program.

Sample Solution:-

Python Code:

from timeit import default_timer
def timer(n):
    start = default_timer()
    # some code here
    for row in range(0,n):
        print(row)
    print(default_timer() - start)

timer(5)
timer(15)

Sample Output:

0

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")
