Python String: Exercise-43 with Solution

Write a Python program to print the square and cube symbol in the area of a rectangle and volume of a cylinder.

Python String Exercises: Print the square and cube symbol in the area of a rectangle and volume of a cylinder

Sample Solution:-

Python Code:

area = 1256.66
volume = 1254.725
decimals = 2
print("The area of the rectangle is {0:.{1}f}cm\u00b2".format(area, decimals))
decimals = 3
print("The volume of the cylinder is {0:.{1}f}cm\u00b3".format(volume, decimals))

Sample Output:

The area of the rectangle is 1256.66cm²                                                                       
The volume of the cylinder is 1254.725cm³

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")
