How do I escape curly-brace ({}) characters in a string while using .format (or an f-string)?

In Python, curly braces {} are used for string formatting, and they can be escaped by using double curly braces {{}}. This is necessary when you want to include literal curly braces in a formatted string without them being interpreted as placeholders. Here's an example using both .format() and f-strings:

Using .format():

python

formatted_string = "This is an example of {{curly braces}} using format method: {}".format(42)
print(formatted_string)

Using f-string:

python

value = 42
formatted_string = f"This is an example of {{curly braces}} using f-string: {value}"
print(formatted_string)

In both cases, the double curly braces {{}} are used to escape the literal curly braces within the string, so they won't be treated as placeholders for string formatting. The output of the above code will be:

This is an example of {curly braces} using f-string: 42
