See more:

Define and implement a function that converts the a list of tuples to a dictionary where the first value of each tuple is the key, and the second value is the dictionary value.

For example, if the user enters the following list: [('Person1', 80), ('Person2', ), ('Person3', 20), ('Person4', 20, 60)]

Then the output should be: {'Person1': 80, 'Person2': None, 'Person3': 20, 'Person4': 20}

What I have tried:

I have tried a few codes but it's giving me an error. I'd appreciate it if you can write the code. Thank you in advance.

Try

Python

lin = [('Person1', 80), ('Person2', ), ('Person3', 20), ('Person4', 20, 60)]
dout = { t[0] : t[1] if len(t) > 1 else None for t in lin}
print(dout)
