Using the Python print() Function to Output Variables

The print() function in Python serves as a primary method for displaying variables and outputs. It is commonly used to print the values of variables to the console during program execution.

Basic Variable Output

To display the value stored in a variable, pass it directly into the print() function:

x = "Python is awesome"
print(x)

Outputting Multiple Variables

Python allows the output of multiple variables in a single line by separating them with commas within the print() function:

x = "Python"
y = "is"
z = "awesome"
print(x, y, z)

This method automatically inserts spaces between the variables.

String Concatenation with the + Operator

Another way to combine multiple strings is by using the + operator, which concatenates the strings manually:

x = "Python "
y = "is "
z = "awesome"
print(x + y + z)

Note: Ensure to include space characters at the end of each string when using +, or the output will appear concatenated without spacing (e.g., Pythonisawesome).

Working with Numbers

When used with numeric variables, the + operator performs mathematical addition:

x = 5
y = 10
print(x + y)

This results in the sum of the two numbers, in this case, 15.

Mixing Strings and Numbers

Attempting to use + to combine a string and a number in Python will raise a TypeError:

x = 5
y = "John"
print(x + y)  # This will cause an error

To output mixed data types correctly, separate them with commas:

x = 5
y = "John"
print(x, y)

This approach handles the different types automatically and prints them in a readable format.
