One built-in function in Python is
print(). The value or expression inside of the parenthesis of a
print() function "prints" out to the REPL when the
print() function is called.
An example using the
print() function is below:
>>> name = "Gabby" >>> print("Your name is: ") Your name is: >>> print(name) Gabby
Remember that strings must be enclosed by quotation marks. The following command produces an error.
>>> print(Gabby) NameError: name 'Gabby' is not defined
This error is corrected by surrounding the string
Gabby with quotation marks.
>>> print("Gabby") Gabby
Expressions passed to the
print() function are evaluated before they are printed out. For instance, the sum of two numbers can be shown with the
>>> print(1+2) 3
If you want to see the text
1+2, you need to define
"1+2" as a string and print out the string
>>> print("1+2") 1+2
Strings can be concatenated (combined) inside of a
>>> name = Gabby >>> print('Your name is: ' + name) Your name is Gabby
print() function also prints out individual expressions one after another with a space in between when the expressions are placed inside the
print() function and separated by a comma.
>>> print("Name:","Gabby","Age", 2+7) Name: Gabby Age 9
