Python print() Function Notes
1. What is the print() Function?
A built-in Python function used to display output on the screen.
Commonly used for debugging and showing results.
Syntax:
python
Copy code
print(object, ..., sep=' ', end='\n', file=sys.stdout, flush=False)
2. Basics of print()
Printing a simple message:
python
Copy code
print("Hello, World!")
Output:
Copy code
Hello, World!
Printing multiple items:
python
Copy code
print("Python", "is", "awesome!")
Output:
csharp
Copy code
Python is awesome!
3. Formatting the Output
Using sep to separate multiple items:
python
Copy code
print("Python", "is", "fun", sep="-")
Output:
kotlin
Copy code
Python-is-fun
Using end to customize line endings:
python
Copy code
print("This is Python", end="!!!\n")
Output:
csharp
Copy code
This is Python!!!
4. Escape Characters
\n: New line
python
Copy code
print("Hello\nWorld")
Output:
Copy code
Hello
World
\t: Tab space
python
Copy code
print("Hello\tWorld")
Output:
Copy code
Hello World
5. Printing Variables
Combine strings and variables:
python
Copy code
name = "John"
age = 25
print("Name:", name, "Age:", age)
Output:
makefile
Copy code
Name: John Age: 25
6. Advanced Usage
Using formatted strings (f-strings):
python
Copy code
name = "Alice"
print(f"Hello, {name}!")
Output:
Copy code
Hello, Alice!
Printing to a file:
python
Copy code
with open("output.txt", "w") as file:
print("Hello, File!", file=file)
7. Common Mistakes to Avoid
Forgetting parentheses (only in Python 3 and newer):
python
Copy code
Correct
print("Hello!")
Error in Python 3+
print "Hello!"
Incorrect use of quotes:
python
Copy code
Correct
print('Hello, World!')
Error: Mismatched quotes
print("Hello, World!')
