String Methods

In Python, strings are like text containers that come with their own set of useful tools. These tools, called string methods, allow you to modify and work with strings in different ways. Here are some commonly used string methods and what they do: 1. ` capitalize() `: Makes the first letter of a string uppercase and the rest lowercase. 2. ` casefold() `: Converts the entire string to lowercase, even handling special cases. 3. ` center(width[, fillchar]) `: Puts a string in the middle of a line of a specific width, optionally filling the extra space with a chosen character. 4. ` count(sub[, start[, end]]) `: Counts how many times a specific part of a string appears within it. 5. ` endswith(suffix[, start[, end]]) `: Checks if a string ends with a particular set of characters and returns True or False. 6. ` find(sub[, start[, end]]) `: Searches for a specific part of a string and tells you where it starts. If not found, it returns -1. 7. ` index(sub[, start[, end]]) `: Similar to `find()...

What is email validation?

Email validation is an interaction that checks whether a particular email address is deliverable. We do not want to send email to anyone who does not have an active email. Sometimes we make typos so the validation engine checks if that particular email domain is reliable like Gmail and Yahoo. Validation engine helps maintain your delivery rate up to 99%. How does it work? 1. SPF SPF allows the collector to browse whether an email claiming to be from a particular domain came from an IP address approved by that domain's administrators. Typically, a domain administrator will authorize the IP addresses used by their own outbound MTAs, including any intermediaries or shining shops. 2. DKIM First, DKIM verifies the content of the message by establishing a digital signature. Second, using digital certificates, signature verification keys are distributed through DNS. Thus, a message is associated with a domain name. 3. DMARC DMARC allows the specification of a policy for message authentica...

Python Variables - Assign Multiple Values

In Python, you can assign multiple values to multiple variables in a single line using the syntax: ``` var1, var2, var3 = value1, value2, value3 ``` This is known as multiple assignment, and it is a convenient way to assign values to multiple variables at once.  The number of variables on the left-hand side of the equals sign must match the number of values on the right-hand side. For example: ``` x, y, z = 1, 2, 3 ``` This assigns the value 1 to variable `x`, the value 2 to variable `y`, and the value 3 to variable `z`. You can also use variables on the right-hand side: ``` a = 1 b = 2 c = 3 x, y, z = a, b, c ``` This assigns the value of `a` to `x`, the value of `b` to `y`, and the value of `c` to `z`.  You can also use a list or tuple on the right-hand side of the equals sign to assign multiple values to multiple variables: ``` values = (1, 2, 3) x, y, z = values ``` This assigns the first value in the tuple to `x`, the second value to `y`, and the third value to `z`. Multi...
