PYTHON PROGRAMMING TUTORIAL: Range Function with example
Introduction
Hello everybody! With this Post I'm starting a series of python basics with examples. In each post I will be taking about one function of python with suitable example.
What you will learn?
You will learn about the range function
You will learn how and where to use range function
Requirements
Basic knowledge of python
Python shell
What is range Function
First let's define what python range function is? In simple words it is define as a function used to generate list of numbers which is generally used to iterate over with for loops.
For example lets say we want to generate numbers between 4 & 20 . we will give a command
range(4,20)
The above command will generate [4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19] list of numbers
The last number (in above case 20 ) is not included.
Parameters of range function
The range function has three parameters namely
start: Starting number of the sequence.
stop: Generate numbers up to, but not including this number.
step: Difference between each number in the sequence.
Note: all parameters must be integers.
If you don't give start and stop parameter then they are 0 & 1 respectively.
Example
Print Numbers Between 0 and 100 which are divisible by 3
For this example things need to be done
*we will use for loop to iterate over the generated list
*we will use if statement to check if number is divisible by 3
*We will print the generated list
for i in range(100): (this line means that we will now iterate over every number one by one )
if i%3==0: ( we are checking if number is divisible by 3)
print(i) (if condition is true it will print i, i.e the number)
That's it for this post guys for the next post I will be talking about how you can do this by defining the function.
I will
