Python: Generate a number in a specified range except some specific numbers
Python List: Exercise - 145 with Solution
Write a Python program to generate a number in a specified range except some specific numbers.
Sample Solution:
Python Code:
from random import choice
def generate_random(start_range, end_range, nums):
result = choice([i for i in range(start_range,end_range) if i not in nums])
return result
start_range = 1
end_range = 10
nums = [2, 9, 10]
print("\nGenerate a number in a specified range (1, 10) except [2, 9, 10]")
print(generate_random(start_range,end_range,nums))
start_range = -5
end_range = 5
nums = [-5,0,4,3,2]
print("\nGenerate a number in a specified range (-5, 5) except [-5,0,4,3,2]")
print(generate_random(start_range,end_range,nums))
Sample Output:
Generate a number in a specified range (1, 10) except [2, 9, 10] 7 Generate a number in a specified range (-5, 5) except [-5,0,4,3,2] -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")
