Functions are logical grouping of code statements that collectively performs a specific operation or a specific requirement. Example: If I am building a calculator, a calculator can perform various mathematical operations like addition, subtraction, division, etc. I can create one function for addition, one function for subtraction, one function for division, and so on. Let’sContinue reading “Functions”

While Loop
While Loops can be used if we need to execute the same set of statements again and again until a condition is met. For example, if we need to print a statement 5 times, we can use while loop. Let’s try to understand with an example: Example: Let’s try to print the value of variableContinue reading “While Loop”
If Statements
Well, if statement is common across many programming languages. When we have scenario, that an action should be performed only after a condition is satisfied, we can use if statement. For example, when a person is trying to login into his gmail account, he has to give his user name and password to validate andContinue reading “If Statements”
Dictionaries
Dictionaries are a bag of key value pairs which is written inside two curly braces. It is a collection of key values pairs that is not ordered, can be changeable and can be indexed. Rather than indexes, in any other collections like lists, arrays, etc., items can be obtained via Key. Now let’s see howContinue reading “Dictionaries”
SETs
Basic explanation of usage of sets in Python
Complex Number
A Complex number is a combination of real number and an imaginary number. For example: 3 + 2i –> This is a complex number in which 3 is the real number and 2i is the imaginary number. i –> is the imaginary number that is imagined as the square root of -1 i.e., √-1. BelowContinue reading “Complex Number”
Data Types
Datatypes are common concepts across every language. The data that is stored in a variable determines the data types. For Example: a variable that stores a text has string as a data type, similarly, variable storing number has int, float or complex as data type depending on the complexity of the number. Let’s understand fewContinue reading “Data Types”
Comments in Python
Comments are statements that is written inside a code which is used mostly for adding the note about the code. Comments doesn’t gets executed. It is basically ignored by the compiler. Comments are added to increase the code readability and maintainability. There are specific syntax that needs to be followed to write comments. Single lineContinue reading “Comments in Python”
Variables in Python
Variable creation in Python is very much similar to the other programming languages. However, there are few notable differences. Variables are created only when it is assigned with a value. There is no concept of declaration. Variables type are determined only when it is assigned with a value. Type is optional while creating variables. TypesContinue reading “Variables in Python”
Indentation in Python
Indentation plays a major role in Python. Let’s see with example. Here is a sample code of if block without space: This says to print “Hello from Python” whenever it executes and both the code statements are aligned to each other. The Python interpreter will not know that the print statement should be executed wheneverContinue reading “Indentation in Python”
