Python Data Types

Python is a dynamically typed language, which means that the data types of variables can change during the execution of the program. Python supports several built-in data types, which can be used to represent different kinds of values. Below are some of the frequently used data types in Python: 1. Numeric Data Types: Python has support for various numeric data types, such as integers, floating-point numbers, and complex numbers. Integers are whole numbers, whereas floating-point numbers are those that contain a decimal point. On the other hand, complex numbers consist of both a real and an imaginary part. Here are some examples: ``` x = 10         # integer y = 3.14       # floating-point number z = 2 + 3j     # complex number ``` 2. String Data Type: Python uses strings to represent text data, which can be encompassed within single quotes ('...') or double quotes ("..."). Here are some examples: ``` a = 'Hello, World!'  ...

Python - Global Variables

In Python, a global variable is a variable that is declared outside of any function and can be accessed by any function in the same module or file. Global variables can be useful for storing values that are needed by multiple functions within the same module or file. In Python, declaring a variable outside of any function is all that's needed to create a global variable: ``` # defining a global variable my_global_var = "Hello World" # Creating a function that utilizes the global variable: def print_global_var():     print(my_global_var) # calling the function print_global_var()  # output: "Hello World" ``` In the example above, `my_global_var` is a global variable that can be accessed by the function `print_global_var()` because it is defined outside of any function. It is also possible to modify the value of a global variable from within a function using the `global` keyword: ``` # defining a global variable my_global_var = "Hello World" # defining a ...

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 ...

Python - Modify Strings

Python -  Modify Strings Python comes with some ready-to-use tools that make working with text easier. Upper Case Example If you apply the upper() method to a string in Python, it will convert all the letters in the string to uppercase and return the modified string: x =   "Hello, World!" print (x. upper() ) Lower Case Example If you apply the  lower()  method to a string in Python, it will convert all the letters in the string to uppercase and return the modified string: x =  "Hello, World!" print (x.lower()) Remove Whitespace The term "whitespace" refers to the space that appears before and/or after the text itself, and it is often desirable to eliminate this space. Example Using the ` strip()` method, you can eliminate any whitespace located at the start or end of a string : x =  " Hello, World! " print (x.strip())  # returns "Hello, World!" Replace String Example With the ` replace() ` method, you can substitute one string with an...
