Answer:

Following are the code to this questiuon:

def fiv(y):#defining a method fiv that hold a parameter

x = str(y) #defining a variable x that convert the value y in string

return three(x[0:3]) and three(x[1:4]) and three(x[2:5])#use return keyword to call the method three

def three(x): #defining a method three that hold x variable as a parameter

y = int(x) #use y to convert x in integer

return y>=100 and (y%17==0 or y%23==0) #use return that gives a value which is divisiable by 17 or 23

print([y for y in range(10000,40000) if fiv(y)])#use print method to print value

Output:

Please find the attached file.

Step-by-step explanation:

In the above code, two methods "fiv and three" is declared that accepts one variable as a parameter, which can be defined as follows:

In the fiv method, an "x" variable is defined that covert the value into a string and use to call the three methods.
Inside the three methods, a y variable is declared, that convert the value into integer and use return keyword, that checks value is divisible by 17 or 23.
In the print method, it accepts the given value, which is passed in the loop to print the value.
