How Do I Escape Curly Braces in Python's .format String Method?

Escaping Curly Braces ({}) in .format Strings

When using the .format method to format strings, curly braces ({}) have a special meaning. They are used to specify replacement fields. However, if you need to include literal curly braces in your string, you can escape them by doubling them ({{ and }}).

Example with Non-Working Double Escaping:

print(" \{ Hello \} {0} ".format(42))

Correct Example with Double Braces:

x = " {{ Hello }} {0} "
print(x.format(42))

Explanation from Python Documentation:

According to the Python documentation:

"Format strings contain “replacement fields” surrounded by curly braces {}. Anything that is not contained in braces is considered literal text, which is copied unchanged to the output. If you need to include a brace character in the literal text, it can be escaped by doubling: {{ and }}."

Therefore, by doubling the curly braces in the correct example, you can escape them and include them as literal text in the string.
