Consider the following functions: def p(n): if n < 10: return 1 return 1 + p(n // 10) def q(n): if n < 10: return n return n % 10 + q(n // 10) def r(n): if n <= 1: return 1 return n * r(n - 1) Which of the following function calls returns the number of digits in 50!, where n! is the factorial of n?
p(q(50))
q(r(50))
p(r(50))
r(q(50))
r(p(50))
Consider the following code snippet that writes student details to a CSV file named "employees.csv": def save_data(data): f = open('employees.csv', 'w') f.write('Name,Salary\n') for i in range(len(data)): emp, sal = data[i] row = f'{emp},{sal}' if i != len(data) - 1: row = row + '\n' f.write(row) f.close() data = [ ('Alice', 75000), ('Bob', 64000), ('Charlie', 82000), ('Diana', 71000), ('Eve', 69000) ] If the save_data(data) function is called with the list data as shown above, what will be the contents of the file "employees.csv"?
Name,Salary Alice,75000 Bob,64000 Charlie,82000 Diana,71000 Eve,69000
Alice,75000 Bob,64000 Charlie,82000 Diana,71000 Eve,69000
Salary,Name Alice,75000 Bob,64000 Charlie,82000 Diana,71000 Eve,69000
Name Salary Alice,75000 Bob,64000 Charlie,82000 Diana,71000 Eve,69000
Salary,Name 75000,Alice 64000,Bob 82000,Charlie 71000,Diana 69000,Eve
What will be the output of the following Python code? string1 = 'database' string2 = 'baseball' L = [] for i in range(len(string1)): for j in range(len(string2)): if string1[i] == string2[j]: L.append(string1[i]) break else: continue print(L)
['a', 'a', 'b', 'a', 's', 'e']
['a', 't', 'a', 'b', 'a', 's', 'e']
['a', 'b', 'a', 's', 'e']
['a', 'a', 'b', 's', 'e']
