In Python3 string.digits — it is a pre-initialized string used as a string constant. In Python, string.digits will produce lowercase letters "0123456789".
Syntax: string.digits
Parameters: Doesn’t take any parameter, since it’s not a function.
Returns: Return all digit letters.
Note. Make sure to import the string library function to use string.digits
Code # 1:
| # import string library function import string
# Store the value as a result of a variable result = string.digits
# Print value print (result) |
Output:
0123456789
Code # 2: this code checks if there are only numbers in the input line
| # import string library function import string
# The function checks if the input line is valid
# har only numbers or not def check (value): for letter in value: # If something other than a number # email is present, then return # False, otherwise return True if letter not in string.digits: return False return True
Driver code input1 = "0123 456 789" print (input1, "-" " , check (input1)) input2 = "12.0124" print (input2, "-"" , check (input2)) input3 = "12345" print (input3, "-"" , check (input3)) |
Exit:
0123 456 789 -" False 12.0124 -" False 12345 -" True
Applications:
Digits string constants can be used in many practical applications.Let’s see the code, explain See how to use numbers to generate strong random passwords of a given size.
| # Import random to generate
# random sequence of lines import random
# Import the string library function import string def rand_pass (size): # Takes a random selection from # ascii_letters and digits < p> generate_pass = ’ ’.join ([random.choice (string.ascii_uppercase + string.ascii_lowercase + string.digits) for n in range (size)]) return generate_pass
Driver code password = rand_pass ( 10 ) print (password) |
