Python Range Function

We begin a function definition with the def keyword,followed by the name we might wish to offer our function.
We’ve the parameters after the name,also called arguments,for the function enclosed in parentheses.
A function may have no parameters,or it can have multiple parameters.
Parameters permit us to call a function and pass it data, with the data being available inside the function as variables with the same name because the parameters.
At the end, we put a colon at the highest of the road .
The function body starts after the colon, .It’s important to note that in Python the function body is delimited by indentation.
This advised that every one code indented to the right following a function definition may be a component of the function body.
The initial line that’s not indented is that the boundary of the function body.It’s up to you ways many spaces you use when indenting—-just inform be consistent.
Hence if we decide on to indent with four spaces, you’d wish to use four spaces everywhere in our code.

A variety () function are often employed by passing it one parameter, and it generated a sequence of numbers from 0 to at least one but we specified.But the range() function can do far more than that.
We would say in two parameters: the primary specifying our start line , the second specifying the top point.
Remember that the sequence generated won’t contain the last element; it’ll stop one before the parameter specified.

The range() function can take a 3rd parameter,too.This third parameter allows you to alter the dimensions of every step. Perhaps than creating a sequence of numbers incremented by 1.
We’ll create a sequence of numbers that are incremented by 5.
One parameter would generate a sequence , one-by-one, from zero to at least one but the parameter.
Two parameters will generate a sequence, one-by-one, from the primary parameter to at least one but the second parameter.
Three parameters would create a sequence starting with the primary parameter and stopping before the second parameter, but this point increasing each step by the third parameter.

We for sometimes do not need a function to easily run and finish.We might want a function to control data we passed it then return the result to us.
This is mostly where the concept of return values comes in handy.We use the return keyword during a function, which tells the function to pass data back.
Once we call the function, we will store the returned value during a variable.
Return values permit our functions to be more flexible and powerful, in order that they are often reused and called multiple times.
Function may even return multiple values.Just do not forget to store all returned values in variables.
We’ll even have a function return nothing, during which case the function simply exits.
