What are the key features of print()?

The print() function in Python has several key features that make it versatile for outputting data. Here are the main features:

Basic Output: It can display strings, numbers, and other data types directly to the console.
```
print("Hello, World!")  # Outputs: Hello, World!
```
Multiple Arguments: You can pass multiple items to print(), and it will automatically add spaces between them.
```
print("The answer is", 42)  # Outputs: The answer is 42
```
String Formatting: Using f-strings (formatted string literals) allows for embedding expressions inside string literals for cleaner output.
```
name = "Alice"
age = 30
print(f"{name} is {age} years old.")  # Outputs: Alice is 30 years old.
```
Custom Separator: The sep parameter allows you to specify a custom string to separate multiple items.
```
print("Hello", "World", sep="-")  # Outputs: Hello-World
```
Custom End Character: The end parameter lets you define what character to print at the end of the output, instead of the default newline.
```
print("Hello", end="!")  # Outputs: Hello!
```

Output to File: You can redirect the output to a file using the file parameter.

with open('output.txt', 'w') as f:
    print("Hello, File!", file=f)  # Writes to output.txt

These features make print() a powerful tool for displaying information in Python programs. If you have any more questions or need examples, feel free to ask!
