Challenge: Implementing a Threshold Checker with Closures
Tarefa
Swipe to start coding
Develop a closure that maintains a state and can be used to perform operations based on that state.
Let's create a closure that checks if a given value exceeds a specified minimum.
- Start by defining the outer function, which we'll name
threshold_checker; - This function should accept a parameter named
threshold; - Next, declare an inner function called
checkwithinthreshold_checker. This inner function should take one parameter,value; - Inside the check function, return True if the value is greater than the threshold, and False otherwise. Use the
<operator for this comparison; - Finally, ensure that the outer function,
threshold_checker, returns the inner functioncheck; - Assign the
threshold_checkerfunction to a variable namedgreater_than_10, passing10as the threshold value; - Run Code and Submit Task.

def threshold_checker(threshold):
def check(value):
return threshold < value
return check
# Usage
greater_than_10 = threshold_checker(10)
print(greater_than_10(12))
print(greater_than_10(8))
