This line of code prints out the value returned via the calculate_grade() perform to the console. We pass through one parameter into our purpose: numerical. This can be the numerical value of the quality a university student has attained.
Not simply Is that this overwriting python's dict, (see mgilson's remark) but This is actually the Completely wrong knowledge construction for your project. You ought to use a list as an alternative (or even a set if you have special unordered values)
We now have established the worth of “numerical†to forty two. Our if assertion will not established a price for virtually any quality around fifty. Therefore whenever we simply call our calculate_grade() purpose, our return statement would not know the value to which we've been referring.
Python has a straightforward rule to find out the scope of a variable. If a variable is assigned inside a perform, that variable is community. This is because it is actually assumed that after you determine a variable within a function You merely ought to access it within that function.
0 When you start introducing features into your code, you’re bound to encounter an UnboundLocalError at some point. This error is lifted any time you attempt to utilize a variable before it has been assigned their website during the neighborhood context.
On this information, we look at what this mistake signifies and why it can be elevated. We stroll by means of an example of this error in action to help you understand how you may address it.

This keyword modifications the scope of our variable to a global variable. This means the “return†assertion will no longer treat “letter†like an area variable. Enable’s operate our code. Our code returns: File.
