Try using triple curly braces. {{ gets converted to a string { (It is an escape sequence).
AccessToken = "AccessTokenValue"
payload={}
headers = { 'authorization': f'{{{AccessToken}}}'}
print(headers)
This will print: {'authorization': '{AccessTokenValue}'}

This is called an f string (hence the f outside the double quotes). The curly brackets surround variables. Another example would be: make = “Jeep” model = “Wrangler” print(f”I drive a {make} {model}.”) Output: I drive a Jeep Wrangler.

March 28, 2023 - As you can see, the double curly braces are interpreted as a single set of curly braces in the output string, while the single curly braces surrounding my_var are interpreted as a format specifier. In conclusion, using double curly braces is an easy way to include curly braces in Python format strings without them being interpreted as format specifiers.

To include literal braces in an f-string, use double braces: # Correct: Escape with double braces name = "Charlie" f_str = f"Hello {{name}}!" # Note: {name} is NOT evaluated here print(f_str) # Output: "Hello {name}!" Here, {{name}} is treated as a literal, so name is not evaluated (unlike {name}, which would insert the variable name).

You need to double the {{ and }}:
>>> x = " {{ Hello }} {0} "
>>> print(x.format(42))
' { Hello } 42 '
Here's the relevant part of the Python documentation for format string syntax:
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}}.

Python 3.6+ (2017)
In the recent versions of Python one would use f-strings (see also PEP498).
With f-strings one should use double {{ or }}
n = 42
print(f" {{Hello}} {n} ")
produces the desired
{Hello} 42
If you need to resolve an expression in the brackets instead of using literal text you'll need three sets of brackets:
hello = "HELLO"
print(f"{{{hello.lower()}}}")
produces
{hello}
