Python program to validate password

Basic conditions for password verification:

At least 8 characters.
Letters must be between [az]
At least one alphabet must be uppercase [AZ]
At least 1 digit or digit between [0-9].
At least 1 character from [_ or @ or $].

Examples:

 Input: R @ m @ _f0rtu9e $ Output: Valid Password Input: Rama_fortune $ Output: Invalid Password Explanation: Number is missing Input: Rama # fortu9e Output: Invalid Password Explanation: Must consist from _ or @ or $

Here we have used the re module which provides support for regular expressions in Python . Along with this the re.search () method returns False (if the first parameter is not found in the second parameter). This method is best for validating a regular expression rather than extracting data. We used re.search () to check if alphabets, numbers or special characters are correct. To check for spaces, we use "/ s" which is included in the regular expression module.

Output:

 Valid Password

I was preparing for my coding interview, thanks for clarifying this - Python program to validate password in Python is not the simplest one. I am just not quite sure it is the best method

Simply put and clear. Thank you for sharing. Python program to validate password and other issues with io Python module was always my weak point 😁. I am just not quite sure it is the best method
