Python string | ascii_uppercase

|

In Python3 ascii_uppercase — it is a pre-initialized string used as a string constant. In Python, the string ascii_uppercase will capitalize & # 39; ABCDEFGHIJKLMNOPQRSTUVWXYZ & # 39 ;.

Syntax: string.ascii_uppercase

Parameters: Doesn’t take any parameter, since it’s not a function.

Returns: Return all uppercase 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_uppercase < / code>

 
# Print value

print (result) 

Output:

 ABCDEFGHIJKLMNOPQRSTUVWXYZ 

Code # 2: This code checks if the line input contains only upper ASCII characters.

# import string library function

import string 

 
# The function checks if the input line is
# has upper ASCII letters or not

def check (value): 

for letter in value: 

 

# If anything then, besides the upper ASCII

# the letter is present, then we return

# False, otherwise return True

  if letter not in string.ascii_uppercase: 

  return False

return True

  Driver code

input1 = "GeeksForGeeks"

print (input1, "-" " , check (input1)) 

  

input2 = "GEEKS FOR GEEKS"

print (input2, "-"" , check (input2)) 

 

input3 = "GEEKSFORGEEKS"

print (input3, "-"" , check (input3)) 

Exit:

 GeeksForGeeks -" False GEEKS FOR GEEKS -" False GEEKSFORGEEKS -" True 

Applications:
String constant ascii_uppercase can be used in many practical applications zheniyah. Let’s see some code explaining how to use ascii_uppercase to generate strong random 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_uppercase + string.digits) 

for n in range (size)]) 

  

return generate_pass 

 
Driver code

password = rand_pass ( 10

print (password)
