collageYou can find comprehensive information about python apostrophe vs quote in the following article. Have you been looking for relevant information online for days? This article is the right place.
In addition to these posts, you will find ones on the following subjects.
Python is the best programming language for making complex code into simpler code. And it’s due to High Level and Just like English language programming language. For example, you want to replace a single quote in the string. If you will use the other programming language you may find difficulty. But in the case of Python, it’s very easy. In this entire tutorial, you will know the various method to replace a single quote from the string using python.
Python Advantages and Disadvantages – Step in the right direction
When you are learning a new language let’s say Python, you must be aware of the benefits and drawbacks of that language.
This will help you to get a better knowledge of how you can take full advantage of the Python programming language.
With knowing the Python advantages and disadvantages, we can build robust applications.
Let’s start with the advantages and disadvantages of Python.
Python Advantages and Disadvantages
Let’s first dive into the advantages of Python.
Advantages of PythonMachine Learning Project Cartoonifier
1. Easy to Read, Learn and Write
Python is a high-level programming language that has English-like syntax.
This makes it easier to read and understand the code.
Python is really easy to pick up and learn, that is why a lot of people recommend Python to beginners.
You need less lines of code to perform the same task as compared to other major languages like C/C++ and Java.
2. Improved Productivity
Python is a very productive language.
Due to the simplicity of Python, developers can focus on solving the problem.
They don’t need to spend too much time in understanding the syntax or behavior of the programming language.
You write less code and get more things done.
3. Interpreted Language
Python is an interpreted language which means that Python directly executes the code line by line.
In case of any error, it stops further execution and reports back the error which has occurred.
Python shows only one error even if the program has multiple errors.
This makes debugging easier.
4. Dynamically Typed
Python doesn’t know the type of variable until we run the code.
It automatically assigns the data type during execution.
The programmer doesn’t need to worry about declaring variables and their data types.
5. Free and Open-Source
Python comes under the OSI approved open-source license.
This makes it free to use and distribute.
You can download the source code, modify it and even distribute your version of Python.
This is useful for organizations that want to modify some specific behavior and use their version for development.
6. Vast Libraries Support
The standard library of Python is huge, you can find almost all the functions needed for your task.
So, you don’t have to depend on external libraries.
But even if you do, a Python package manager (pip) makes things easier to import other great packages from the Python package index (PyPi).
It consists of over 200,000 packages.
7. Portability
In many languages like C/C++, you need to change your code to run the program on different platforms.
That is not the same with Python.
You only write once and run it anywhere.
However, you should be careful not to include any system-dependent features.
Disadvantages of Python
1. Slow Speed
We discussed above that Python is an interpreted language and dynamically-typed language.
The line by line execution of code often leads to slow execution.
The dynamic nature of Python is also responsible for the slow speed of Python because it has to do the extra work while executing code.
So, Python is not used for purposes where speed is an important aspect of the project.
2. Not Memory Efficient
To provide simplicity to the developer, Python has to do a little tradeoff.
The Python programming language uses a large amount of memory.
This can be a disadvantage while building applications when we prefer memory optimization.
3. Weak in Mobile Computing
Python is generally used in server-side programming.
We don’t get to see Python on the client-side or mobile applications because of the following reasons.
Python is not memory efficient and it has slow processing power as compared to other languages.
4. Database Access
Programming in Python is easy and stress-free.
But when we are interacting with the database, it lacks behind.
The Python’s database access layer is primitive and underdeveloped in comparison to the popular technologies like JDBC and ODBC.
Huge enterprises need smooth interaction of complex legacy data and Python is thus rarely used in enterprises.
5. Runtime Errors
As we know Python is a dynamically typed language so the data type of a variable can change anytime.
A variable containing integer number may hold a string in the future, which can lead to Runtime Errors.
Therefore Python programmers need to perform thorough testing of the applications.
What are single quotes used for in Python?
Single quotes are used to mark a quote within a quote or a direct quote in a news story headline.Play Video
When programming with Python, we generally use single quotes for string literals. For example – ‘my-identifier’. Let us understand with an example through code in Python.
NOTE: Always make use of single quotes when you know your string may contain double quotes within.
Example usage of single quotes in Python
Below is the code where you can see the implementation of single quote.
word = 'Ask?' print(word) sentence = 'Python Programming' print(sentence) name = '"Hi" ABC' print(name) congrat = 'We congrat's you.' print(congrat)
Output
Ask? Python Programming "Hi" ABC Invalid Syntax
What are double quotes in Python used for?
A double quotation mark is to set off a direct (word-for-word) quotation. For example – “I hope you will be here,” he said. In Python Programming, we use Double Quotes for string representation. Let us understand with an example through code in python.
NOTE: Use double quotes to enclose your strings when you know there are going to be single quotes within your string
Code
wish = "Hello World!" print(wish) hey = "AskPython says "Hi"" print(hey) famous ="'Taj Mahal' is in Agra." print(famous)
Output
Hello World! Invalid Syntax 'Taj Mahal' is in Agra.
Key Differences Between Single and Double Quotes in Python
| Single Quotation Mark | Double Quotation Mark |
| Represented as ‘ ‘ | Represented as ” “ |
| Single quotes for anything that behaves like an Identifier. | Double quotes generally we used for text. |
| Single quotes are used for regular expressions, dict keys or SQL. | Double quotes are used for string representation. |
| Eg. ‘We “welcome” you.’ | Eg. “Hello it’s me.” |
Bonus – Triple Quotes in Python
What if you have to use strings that may include both single and double quotes? For this, Python allows you to use triple quotes. A simple example for the same is shown below. Triple quotes also allow you to add multi-line strings to Python variables instead of being limited to single lines.
Example of triple quotes
sentence1 = '''He asked, "did you speak with him?"''' print(sentence1) sentence2 = '''"That's great", she said.''' print(sentence2)
Output:
He asked, "did you speak with him?" "That's great", she said.
As you can see, Python now understands that the double and single quotes are part of the string and do not need to be escaped.
Summary
Python is a simple, versatile and a complete programming language.
It is a great choice for beginners up to professionals.
Although it has some disadvantages, we can observe that the advantages exceed the disadvantages.
Even Google has made Python one of its primary programming languages.
I hope that our article was useful to you.
