hi @rajputsafal27
try this code : url= “https://min-api.cryptocompare.com/data/price?fsym=BTC&tsyms={}".format("currency.upper”)

You could also check this documentation for formatting the URL string to include your input.
Also I think you have missed the ‘&t’ in the URL.
Hope this works!

A KeyError in Python is raised when you try to access a dictionary key that doesn’t exist in the dictionary. This error occurs when you try to access a dictionary value using a key that doesn’t exist in the dictionary. The error message typically includes the name of the key that was not found in the dictionary.

To handle this error, you can either check if the key exists in the Python dictionary before trying to access it, or use the .get() method which allows you to specify a default value to return if the key does not exist in the dictionary.

my_dict = {"a": 1, "b": 2}
if "c" in my_dict:
    print(my_dict["c"])
else:
    print("Key 'c' not found in the dictionary")

As you mentioned, a KeyError occurs when you try to access a dictionary key that doesn’t exist in the dictionary. To fix this error, you can either check if the key exists in the dictionary before trying to access it or use the .get() method.
