In Python3 ascii_lowercase — it is a pre-initialized string used as a string constant. In Python, the string ascii_lowercase will give lowercase letters "abcdefghijklmnopqrstuvwxyz".
Syntax: string.ascii_lowercase
Parameters: Doesn’t take any parameter, since it’s not a function.
Returns: Return all lowercase letters.
Note. Make sure to import the string library function to use ascii_lowercase.
Code # 1:
| # import string library function import string
# Store the value as a result of a variable result = string.ascii_lowercase < / p>
# Print value print (result) |
Output:
abcdefghijklmnopqrstuvwxyz
Code # 2: This code checks if the input contains a string lower ASCII characters only.
| # import string library function import string
# The function checks whether the input line is
# has only lower ASCII letters or not def check (value): for letter in value: # If anything , except for lower ASCII # the letter is present, then return # False otherwise return True if letter not in string.ascii_lowercase: return False return True
Driver code input1 = "GeeksForGeeks" print (input1, "-" " , check (input1)) input2 = "geeks for geeks" print (input2, "-"" , check (input2)) input3 = "pythonengineering" print (input3, "-"" , check (input3)) |
Exit:
GeeksForGeeks -" False geeks for geeks -" False pythonengineering -" True
Applications:
String constant ascii_lowercase can be used in many practical applications zheniyah. Let’s see some code explaining how to use ascii_lowercase to generate random strong passwords of a given size.
| # Import random to generate
# random sequence of lines import random
# Import string library function import string def rand_pass (size): # Takes a random selection from # ascii_letters and digits generate_pass = ’’ .join ([random.choice ( string.ascii_lowercase + string.digits) for n in range (size)]) return generate_pass
Driver code password = rand_pass ( 10 ) print (password) |
