Python comment

Python comments are used to provide additional information about your code, and they are not executed by the Python interpreter. There are two types of comments in Python: single-line comments and multi-line comments.

Single-line comments begin with the hash symbol (#) and continue until the end of the line. They are often used to explain what a particular line of code does. For example:


```
# This line prints 'Hello, world!'
print("Hello, world!")
```

Multi-line comments, also known as block comments, are used to provide more detailed explanations of code. They start and end with three consecutive quotation marks (""") and can span multiple lines. For example:

```
"""
This is an example of a multi-line comment. It can be used to provide more detailed explanations of code or to temporarily disable a section of code.

print("This code is currently disabled.")
"""

print("Hello, world!")
```

It is important to use comments in your code to make it more understandable and easier to maintain. Well-written comments can help you and other developers understand the purpose and functionality of your code, making it easier to modify or update in the future.

There are different ways to comment multiple lines of code in Python depending on the text editor or IDE you are using. Here are some common methods:


1. Comment multiple lines shortcut on Mac:

On Mac, you can use the following shortcut to comment multiple lines in Python:
- Select the lines of code you want to comment
- Press the keys "Command" and "/" at the same time
This will add the hash symbol (#) to the beginning of each line, commenting them out.

2. Comment multiple lines in Python VSCode:

In Visual Studio Code, you can comment multiple lines of code in Python using the following steps:
- Select the lines of code you want to comment
- Press the keys "Command" and "K" followed by "Command" and "C" on Mac, or "Ctrl" and "K" followed by "Ctrl" and "C" on Windows/Linux
This will comment out the selected lines using the hash symbol (#).

3. Comment multiple lines shortcut in PyCharm:

In PyCharm, you can use the following shortcut to comment multiple lines of code in Python:
- Select the lines of code you want to comment
- Press the keys "Command" and "/" on Mac, or "Ctrl" and "/" on Windows/Linux
This will add the hash symbol (#) to the beginning of each line, commenting them out.

It's important to note that Python comments end at the end of the line, so any code after the comment on the same line will not be executed. Additionally, commenting out code can be useful for debugging or temporarily disabling sections of code, but it's generally not recommended to leave commented-out code in your program for long periods of time as it can clutter your code and make it harder to read.

Python Strings

Python is a computer language that can be used for many things like creating websites, studying data, and building smart machines. Strings are an important way of storing and working with text in Python. This piece of writing will cover the basics of strings, including their definition, how they can be made, and a few typical actions you can do with them. What are Strings in Python? Python considers a string as a series of characters that signify text-based data. Such a string is composed of a group of characters that are enclosed either in single quotes ('') or double quotes (""). Strings can contain letters, numbers, symbols, and spaces, and can be of any length. For instance, "Hello, World!" is a valid string, as are 'Python is awesome!' and "12345". The choice of quotes is yours to make, as long as you're consistent. In Python, if a string begins with a single quote, it must be terminated with a single quote. Similarly, if a string ...

What is meant by inbox placement rate?

Email is the most productive promotional channel with an average ROI of 145%. Sellthrough has written multiple ebooks on how to make progress on this over the years, focusing on techniques like personalization and behavior-based trigger messages. However, your email marketing program will only have a significant impact on your brand's bottom line if your messages are actually received. Many marketers don't realize that deliverability and revenue have a much more symbiotic relationship. Consistently, people receive more than 300 billion messages, which is 0.02% of the message volume actually sent. Concerned with securing clients' inboxes as a matter of first importance, Internet Service Providers (ISPs) identify most messages as malicious spam, blocking them out and out. ISPs rule on caution and cast a wide net, giving comparable treatment to any email that appears to resemble spam. As indicated by Return Path's 2018 Deliverability Benchmark Report, the typical inbox pla...
