Answer:
Here is the getInRange() function:
def getInRange(x,a,b):
lower = min(a,b)
upper = max(a,b)
if(x<lower):
x = lower
elif(x>upper):
x = upper
return x
Explanation:
Here is the complete program if you want to take the input float values for x, a and b from user:
x = float(input("Enter x: ")) #prompts user to input float value of x
a = float(input("Enter a: ")) #prompts user to input float value of a
b = float(input("Enter b: ")) #prompts user to input float value of b
def getInRange(x,a,b): #function definition
lower = min(a,b) #computes minimum of a and b and store it to lower
upper = max(a,b) #computes maximum of a and b and store it to upper
if(x<lower): #if value of x is less than lower bound
x = lower # return the lower bound by assigning the value of lower to x
elif(x>upper): #if value of x is greater than upper bound
x = upper #return the upper bound by assigning value of upper to x
return x #function returns the value of x
print(getInRange(x,a,b)) #calls function by passing values for x, a and b and print the result on output screen
I will explain this function with an example:
Suppose
x = 1.1
a = 3.3
b = 5.6
Now the method getInRange takes these three values as parameter and works as follows:
lower = min(a,b)
This statement computes the minimum value of a and b by using min() method and sets the resultant value to lower variable. This becomes:
lower = min(3.3,5.6)
Since 3.3 is less than 5.6 so minimum value is 3.3 Hence
lower = 3.3
upper = max(a,b)
This statement computes the maximum value of a and b by using max() method and sets the resultant value to upper variable. This becomes:
upper= max(3.3,5.6)
Since 5.6 is greater than 3.3 so maximum value is 5.6 Hence
upper = 5.6
if(x<lower):
This statement checks if the value of x is less than value of lower
Since x = 1.1 and lower = 3.3 So, 1.1 is less than 3.3
This means the statement inside this if statement executes:
x = lower
So the value of lower is set to x, So
x = 3.3
Now the elif part will not execute. Program moves to the following statement:
return x
This will return the value of x i.e. 3.3
print(getInRange(x,a,b))
This statement calls getInRange() method and prints the result on screen. So the output of the above program with input is:
Enter x: 1.1 Enter a: 3.3 Enter b: 5.6 3.3
