Python: Generate a random integer and date
Python module: Exercise-5 with Solution
Write a Python program to generate a random integer between 0 and 6 - excluding 6, random integer between 5 and 10 - excluding 10, random integer between 0 and 10, with a step of 3 and random date between two dates.
Use random.randrange()
Sample Solution:
Python Code:
import random
import datetime
print("Generate a random integer between 0 and 6:")
print(random.randrange(5))
print("Generate random integer between 5 and 10, excluding 10:")
print(random.randrange(start=5, stop=10))
print("Generate random integer between 0 and 10, with a step of 3:")
print(random.randrange(start=0, stop=10, step=3))
print("\nRandom date between two dates:")
start_dt = datetime.date(2019, 2, 1)
end_dt = datetime.date(2019, 3, 1)
time_between_dates = end_dt - start_dt
days_between_dates = time_between_dates.days
random_number_of_days = random.randrange(days_between_dates)
random_date = start_dt + datetime.timedelta(days=random_number_of_days)
print(random_date)
Sample Output:
Generate a random integer between 0 and 6: 0 Generate random integer between 5 and 10, excluding 10: 5 Generate random integer between 0 and 10, with a step of 3: 3 Random date between two dates: 2019-02-17

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")
