Python: Generate a random float within a specific range

Python module: Exercise-7 with Solution

Write a Python program to generate a float between 0 and 1, inclusive and generate a random float within a specific range.

Use random.uniform

Sample Solution:

Python Code:

import random 
print("Generate a float between 0 and 1, inclusive:")
print(random.uniform(0, 1))
print("\nGenerate a random float within a range:")
random_float = random.uniform(1.0, 3.0)
print(random_float)

Sample Output: 

Generate a float between 0 and 1, inclusive:
0.9332552133311842

Generate a random float within a range:
1.3166101982165992

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")
