# 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 specify where the values should be substituted, and the arguments passed to the function are inserted in order at the specified locations.

```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 dynamic strings, where the string may change based on variables, etc.

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.
