raw_input() function is used to accept user input.It presents a prompt to the user , gets input from the user and returns the data input by the user in a string. It is available in Python 2. x only, and is renamed to input() from Python 3. x version. Hence, in Python 3.
Basically, the difference between raw_input and input is that the return type of raw_input is always string, while the return type of input need not be string only. Python will judge as to what data type will it fit the best. ... But if it is raw_input it would certainly be string.
Python has many built-in functions; you can also create your own. Python has an input function which lets you ask a user for some text input. ... The program will resume once the user presses the ENTER or RETURN key. Look at this example to get input from the keyboard using Python 2 in the interactive mode.
Python user input from the keyboard can be read using the input() built-in function. The input from the user is read as a string and can be assigned to a variable. After entering the value from the keyboard, we have to press the “Enter” button. Then the input() function reads the value entered by the user.
Defining a Function You can define functions to provide the required functionality. Here are simple rules to define a function in Python. Function blocks begin with the keyword def followed by the function name and parentheses ( ( ) ). Any input parameters or arguments should be placed within these parentheses.
Whatever you enter as input, the input function converts it into a string. If you enter an integer value still input() function convert it into a string. Parameter: Prompt: (optional) The string that is written to standard output(usually screen) without newline.
The input() method reads a line from the input (usually from the user), converts the line into a string by removing the trailing newline, and returns it.
An "if statement" is written by using the if keyword....Python supports the usual logical conditions from mathematics:
loop forever
+= adds a number to a variable, changing the variable itself in the process (whereas + would not). Similar to this, there are the following that also modifies the variable: -= , subtracts a value from variable, setting the variable to the result. *= , multiplies the variable and a value, making the outcome the variable.
The while (condition) is very clear on the conditions which continue the loop, etc. That doesn't mean break is wrong, just can be less readable. ... if you don't use other breaks in the loop code, there's only one exit point in your loop and that's the while() condition.
else if
The equality operator doens't set any value, it only checks whether two values are equal. = is assignment of right side operand to the left hand operand. == is used for checking value of an operand. It is generally used for some decision making and accordingly defining action.
1. There can be multiple 'elif' blocks, however there is only 'else' block is allowed. ... Out of all these blocks only one block_of_code gets executed. If the condition is true then the code inside 'if' gets executed, if condition is false then the next condition(associated with elif) is evaluated and so on.
Python is an advanced scripting language that is being used successfully to glue together large software components. It spans multiple platforms, middleware products, and application domains. Python is an object-oriented language with high-level data structures, dynamic typing, and dynamic binding.
Python is developed under an OSI-approved open source license, making it freely usable and distributable, even for commercial use. Python's license is administered by the Python Software Foundation.
You can be on your own with Python analyzing data. It is more like a solo thing, generally. It's part of the reason why it's become one of the fastest-growing languages, and one of the most in-demand languages. So it's a good place to start.
It's often used as a “scripting language” for web applications. This means that it can automate specific series of tasks, making it more efficient. Consequently, Python (and languages like it) is often used in software applications, pages within a web browser, the shells of operating systems and some games.
Java may be a more popular option, but Python is widely used. People from outside the development industry have also used Python for various organizational purposes. Similarly, Java is comparatively faster, but Python is better for lengthy programs.
Although it's not as popular as C++ with DirectX and OpenGL, Python does support game development. ... PyGame is a library that is developer-friendly and easy to use for building games. Python is an easy language to start with, so building games in Python is not a hard thing to do either.
Let' see some of the disadvantages of Python. Speed: Python is interpreted language and is slow as compared to C/C++ or Java. Unlike C or C++ it's not closer to hardware because Python is a high-level language. ... Memory Consumption: For any memory intensive tasks Python is not a good choice.
Python is a more popular language over C++ for AI and leads with a 57% vote among developers. That is because Python is easy to learn and implement. With its many libraries, they can also be used for data analysis.
On average it takes about 6-8 weeks to learn the basics. This gets you enough time to understand most lines of code in Python. If you want to become an expert in Python and its field and plan on getting into data science then months and years of learning is needed.
One Month Goal:
You can easily start if you have some basic know-how of English and mathematics. Students still start with a procedural set of statically typed languages like C, C++, Java or Pascal. Students can still choose PYTHON as their first language, even without any programming background.
Learn The Python Programming Language Fast Concepts are presented in a "to-the-point" style to cater to the busy individual. With this book, you can learn Python in just one day and start coding immediately.
