Variables

In Python, variables are defined with certain rules. 




Let's get started reading about them!! 

  • Don't create variable with a number
    • Eg: '12a'; #is wrong.
  • Don't define any variables with space, instead we can define with intend mark.
    • Eg: new word = Hello ; #is wrong
    • new_word = Hello ; #is correct

  • Don't create any variable contain any of these symbols:

    :'",<>/?|\!@#%^&*~-+

  • it's considered best practice (PEP8) that names are lowercase with underscores

  • avoid using Python built-in keywords
    • built-in keywords like list and str
  • avoid using the single characters l (lowercase letter el), O (uppercase letter oh) and I (uppercase letter eye) as they can be confused with 1 and 0

Strings

Strings are used in Python to record text information, such as names.  Strings in Python are actually a sequence, which basically means Python keeps track of every element in the string as a sequence.  For example, Python understands the string "hello' to be a sequence of letters in a specific order. This means we will be able to use indexing to grab particular letters (like the first letter, or the last letter). This idea of a sequence is an important one in Python and we will touch upon it later on in the future. In this blog we'll learn about the following: Creating Strings Printing Strings String Methods String Indexing String Slicing String Properties Creating String: 1] Strings can be created as below using single quotes or double quotes strVar = 'Python' strVar1 = "python" 2] A multi-line string can declared with triple quotes as below: strVar2 = """python language is easy to learn""" 3] A...

Numbers

In this blog, we will learn about numbers in Python and how to use them. Types of Numbers: Python has various "types" of numbers (numeric literals). We'll mainly focus on integers and floating point numbers . Integers are just whole numbers, positive or negative. For example: 2 and -2 are examples of integers. Floating point numbers in Python are notable because they have a decimal point in them, or use an exponential (e) to define the number. For example 2.0 and -2.1 are examples of floating point numbers. 4E2 (4 times 10 to the power of 2) is also an example of a floating point number in Python. we can do basic arithmetic function in python . See the below examples. # Addition  2+1 o/p - 3 # Subtraction  2-1 o/p - 1 # Multiplication  2*2 o/p - 4 # Division  3/2 o/p - 1.5 Note: Python 2 treats numbers that you type without any digits after the decimal point as integers, which can lead to some unexpected results during division. For example, if you ...
