Python: Generate a random color hex, alphabetical string, random value and multiple of 7
Python module: Exercise-1 with Solution
Write a Python program to generate a random color hex, a random alphabetical string, random value between two integers (inclusive) and a random multiple of 7 between 0 and 70.
Use random.randint()
Sample Solution:
Python Code:
import random
import string
print("Generate a random color hex:")
print("#{:06x}".format(random.randint(0, 0xFFFFFF)))
print("\nGenerate a random alphabetical string:")
max_length = 255
s = ""
for i in range(random.randint(1, max_length)):
s += random.choice(string.ascii_letters)
print(s)
print("Generate a random value between two integers, inclusive:")
print(random.randint(0, 10))
print(random.randint(-7, 7))
print(random.randint(1, 1))
print("Generate a random multiple of 7 between 0 and 70:")
print(random.randint(0, 10) * 7)
Sample Output:
Generate a random color hex: #eb76d4 Generate a random alphabetical string: lGhPpBDqfCgXKzSbGcnmcDWBEZeiqcUqztgvwcXfVyPslOggKdbIxOejJfFMgspqrgskanNYpscJEOVIpYkGGNxQlaqeeubGDbQSBhBedrdOyqOmKPTZvzKmKVoidsuShSCapEXxxNJRCxXOwYUUPBefKmJiidGxHwvOxAEujZGjJjTqjRtuEXgyRsPQpqlqOJJjKHAPHmIJLpMvLTRVqwSeLCIDRdMnYpbg Generate a random value between two integers, inclusive: 0 4 1 Generate a random multiple of 7 between 0 and 70: 70

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")
