# Example of string formatting using the format() function in Python

# Variable declaration
name = "Anna"
date = "Wednesday"
temp = 23.5

# String formatting using the format() function
welcome = """
Hello, {0}!
Today is {1}, and the temperature is {2} degrees.
"""

formatted = welcome.format(name, date, temp)

print(formatted)

# Inserting Variables into Strings with the format() Function 

The `format()` function is used to insert variables or values into a string.

The format function uses curly braces `{ }` within the string to indicate where values should be inserted. The arguments passed to the function are placed in the specified locations in the order they appear.

```python title="Using the format() Function"
greeting = "Hello, {0}! Today is {1}."

formatted_greeting = greeting.format("CodeFriend", "Tuesday")

print(formatted_greeting)  # "Hello, CodeFriend! Today is Tuesday."
```

<br />

The format() function is useful for creating dynamic strings, allowing the content to change based on variables and other input.

The format() function inserts values into curly braces in order. For example, {0} and {1} contain the first and second arguments of the format function.
