## Requirements and Specifications     Source Code

```PROGRAM 1 cwid = input('Please, enter CWID: ') f = open('students.txt', 'r') lines = f.read().splitlines() line_counter = 0 found_name = None while line_counter < len(lines):     if lines[line_counter] == cwid:         found_name = lines[line_counter + 1]         break     line_counter += 2 if found_name:     print(found_name) ```

PROGRAM 2

```import random num = int(input('Please, enter the number: ')) rand_list = [] for i in range(num):     rand_list.append(random.randint(0, 1000)) total = 0 min1 = None max1 = None for a in rand_list:     total += a     if not min1 or min1 > a:         min1 = a     if not max1 or max1 < a:         max1 = a print('The sum of the elements is:', total) print('The biggest number is:', max1) print('The smallest number is:', min1) ```

PROGRAM 3

```s = "112233445566778899 Saturn V rocket's first stage carries 203400 gallons or 770000 liters of kerosene fuel and " \     "318000 gallons of liquid oxygen needed for combustion. At liftoff, the stage's five F1 rocket engines ignite and " \     "produce 7 million pounds of thrust. " tokens = s.split() numbers = [] words = [] for token in tokens:     if token.isnumeric():         numbers.append(token)     else:         words.append(token) print(words, '\n') print(numbers) ```

PROGRAM 4

```def calculate_monthly_costs(car_loan, mortgage, insurance, gas, groceries):     total = car_loan + mortgage + insurance + gas + groceries     return total def main():     car_loan = 50.0     mortgage = 40.0     insurance = 20.0     gas = 30.0     groceries = 10.0     monthly_cost = calculate_monthly_costs(car_loan, mortgage, insurance, gas, groceries)     print('{:.2f}'.format(monthly_cost)) main()```
