Python string | ascii_lowercase

|

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)
