Study Notes
The Print Statement in Python
- The print statement is used to output a value to the user as a program output.
- The simplest form of the print statement is
print(value), wherevalueis the value to be printed.
Printing Strings
- Strings are sequences of characters enclosed in quote marks (either single quotes or double quotes).
- Examples:
print("hello")orprint('hello')
Printing Non-String Values
- Non-string values (e.g., numbers) do not need quote marks.
- Examples:
print(10),print(10 + 1),print(True)
Printing Multiple Values
- Multiple values can be printed by separating them with commas.
- The print statement will add a space character between each value.
String Formatting
- Placeholders can be used in a string, and replaced with actual values using the
format()function. - Example:
print("My name is {} and I am {} years old.".format("James", 15))
Literals and Variables
- A literal is a value itself (e.g.,
10or"hello"). - A variable is a label assigned to a value, allowing it to be reused in the program.
Using Variables
- Variables can be used in place of literals in print statements.
- Example:
name = "James"; age = 15; profession = "student"; print("My name is {} and I am {} years old. I am a {}.".format(name, age, profession))
Benefits of Variables
- Variables allow for easy changes to the program without modifying the code.
- Variables can be used to store complex expressions or values, making the code more readable.
