Python: Generate a random alphabetical character, string and alphabetical string of a fixed length

Python module: Exercise-3 with Solution

Write a Python program to generate a random alphabetical character, alphabetical string and alphabetical string of a fixed length.

Use random.choice

Sample Solution:

Python Code:

import random
import string
print("Generate a random alphabetical character:")
print(random.choice(string.ascii_letters))
print("\nGenerate a random alphabetical string:")
max_length = 255
str1 = ""
for i in range(random.randint(1, max_length)):
    str1 += random.choice(string.ascii_letters)
print(str1)
print("\nGenerate a random alphabetical string of a fixed length:")
str1 = ""
for i in range(10):
    str1 += random.choice(string.ascii_letters)
print(str1)

Sample Output:

Python: Tips of the Day

For-else construct useful when searched for something and find it:

# For example assume that I need to search through a list and process each item until a flag item is found and 
# then stop processing. If the flag item is missing then an exception needs to be raised.

for i in mylist:
    if i == theflag:
        break
    process(i)
else:
    raise ValueError("List argument missing terminal flag.")
