Let’s start the lesson with an example,

        

#Example program
print("Hi friends!")

This code prints "Hi friends!" to the screen.

print() function:

The print() function helps to print a string or variable or anything to a screen. If you want to give more than one value, you could use a comma to separate them.

Syntax:

print(var1,var2,"string",...[end="",sep=" ",file=file,flush=flush])

In above inside square brackets are optional.

Parameters:

var1,var2

These can be values or variables or expressions to display.

end

It decides to finish a print() with the given value. (Default value is "\n")

sep

sep is a separator for given arguments of the print() function. (Default value is " ")

Printing some values:

>>>print("Learnallsimply")
Learnallsimply
>>>print(10+10)
20

In the above, we printed a string and a maths operation.

Using separator:

>>>print("Hi","friends!",sep="|")
Hi|friends!
>>>print("Welcome","to","all",sep="\n")
Welcome
to
all
>>>

In the above snippet, we separated all given strings using 'sep'. '\\n' is one of the escape sequences. It returns a new line to a screen. We will learn about that in later lessons.

Using end:

Have a look at the below code

#In a script mode
print("Hi")
print("friends!")

Output:

Hi
friends!

In the above example, the print function printed them between a new line. Suppose if we want to make thems ends with a comma or anything? "end" makes these situations easy.

#In a script mode
print("Hi",end=",")
print("friends!",end="👍")

Output:

Hi,friends!👍

Here a first string ends with a comma and a second string is ends with thumbs up.
