The spaces at the beginning of a code line is called as Identation. In other Programming languages Identation or Spaces in the beginning of the code if just for readability but In Python it makes difference. The indentation in Python is very important. Python uses indentation to indicate a block of code. For Example: if 5 > 2:  print("Five is greater than two!") In above example when...

Like other programming languages Python also has commenting capability for the purpose of in-code documentation. Single Line Comment: Comments start with a #, and Python will render the rest of the line as a comment:  Example: #This is a comment. print("Hello, World!") Or print("Hello, World!") #This is a comment Multy-Line Comment: In-fact Python does not have any syntax for multi-line...

Basically, Python has no command to Declare a Variable. A Variable is created as soon as you assign any value to it. Whether it is numeric, String, Float, Boolean or any kind. Variables do not need to be declared with any particular type, and can even change type after they have been set. *** Variable names in Python are case-sensitive. A variable can have a short name (like x and y) or a more...

Python allows to assign multiple values to multiple variables in a single line as shown in Example below: x, y, z = "Bus", "Car", "Jeep"print(x)print(y)print(z) Python also allows to assign same value to multiple variables in a single line as shown in example below: x = y = z = "Vehicles"print(x)print(y)print(z)

Those Variables which you create outside of a function are by-default global variables. This means that these variables can be used inside an outside functions.Example: x = " X is global variable."def myfunc():  print("Wow!! " + x)myfunc() If you create a variable with the same name inside a function, this variable will be local, and can only be used inside the...

Python Arithmetic Operators Operator Name Example + Addition x + y - Subtraction x - y * Multiplication x * y / Division x / y % Modulus x % y ** Exponentiation x ** y // Floor division x // y Python Assignment Operators Operator Example Same As = x = 5 x = 5 += x += 5 x = x + 5 -= x -= 5 x = x - 5 *= x *= 5 x = x * 5 /= x /= 5 x = x / 5 %= x %= 5 x = x % 5...
