Required python program as below:

# This is a function definition. You can ignore this for now.
def parse_integer_list_from_string(string):
# Split the line into a list of strings, each containing a number.
number_string_list = string.split()
# Create an empty list to store the numbers as integers.
numbers = []
# Convert each string to an integer and add it to the list of numbers.
for number_string in number_string_list:
numbers.append(int(number_string))
# Return the list of integers
return numbers

# Prompt the user to enter a single line of integers separated by spaces.
# Assign the list of integers to number_list. Print the resulting list.
number_list = parse_integer_list_from_string(input('Numbers?\n'))
print(number_list)
# Do not edit any of the code above this line.

# Test cases:
# [1, 5, 99, 22, 3] -> 99
# [111, 4444] -> -1
# [44, 16, 8, 74] -> 74
# Pseudocode:

# 1) Print the largest two digit number in number_list. If there are no
# two digits numbers in the list, print -1.
# Assign max_number to -1

# Loop through the numbers
for number in number_list:

if number>max_number and 10<=number<=99:
# Assign number to max_number
max_number = number
# Print max_number
print(max_number)

# 2) Swap the largest number in the list with
# the smallest number in the list. Print number_list.
# [23, 500, 99] -> [500, 23, 99]

print(number_list)

# 3) Print the median of number_list.
