Hello, please help me to answers my assignment I highly appreciate you effort. Thanks in advanced.

3. A built-in function is a function which:

a.) has to be imported before use b.) comes with Python, and is an integral part of Python c.) is hidden from programmers d.) has been placed within your code by another programmer

4. The fact that tuples belong to sequence types means:

a.) they can be extended using the .append() method b.) they can be indexed and sliced like lists c.) they can be modified using the del instruction d.) they are actually lists

5. What is the output of the following snippet?

a.) 3 b.) 1 c.) 6 d.) the code is erroneous

6. What is the output of the following snippet?

def fun(x): x += 1 return x x = 2 x = fun(x+1) print(x) a.) 3 b.) the code is erroneous c.) 5 d.) 4

7. What code would you insert into the commented line to obtain the output that reads:

a b c

Code:

dct = { } lst = ['a','b','c','d'] for i in range(len(lst) - 1): dct[lst[i]] = ( lst[i], ) for i in sorted(dct.keys()): k = dct[i] # insert your code

a.) print(k[0]) b.) print(k) c.) print(k['0']) d.) print(k["0"])

8. The following snippet:

def func(a,b): return a ** a print(func(2))

a.) is erroneous b.) will output 2 c.) will output 4 d.) will return None

9. The following snippet:

def func1(a): return a ** a def func2(a): return func1(a)*func1(a) print(func2(2)) a.) is erroneous b.) will output 4 c.) will output 2 d.) will output 16

10. Which of the following lines properly starts a function using two parameters, both with zeroed default values?

a.) def fun(a=b=0): b.) fun fun(a=0,b): c.) def fun(a=0,b=0): d.) fun fun(a,b=0):

11. Which of the following statements is false?

a.) The None value cannot be used as an argument of arithmetic operators b.) The None value can be compared with variables c.) The None value may not be used outside functions d.) The None value can be assigned to variables

12. What is the output of the following snippet?

def fun(x): if x % 2 == 0: return 1 else: return print(fun(fun(2)) + 1)

a.) 1 b.) 2 c.) None d.) the code will cause a runtime error

13. What is the output of the following snippet?

def fun(x): global y y = x * x return y fun(2) print(y)

a.) 4 b.) the code will cause a runtime error c.) 2 d.) None

14. What is the output of the following snippet?

def any(): print(var + 1,end='') var = 1 any() print(var) a.) 22 b.) 12 c.) 11 d.) 21

15.Assuming that tuple is a correctly created tuple, the fact that tuples are immutable means that the following instruction:

tuple[1] = tuple[1] + tuple[0]

a.) is illegal b.) is fully correct c.) can be executed if and only if the tuple contains at least two elements d.) may be illegal if the tuple contains strings

16. What is the output of the following snippet?

list = ['Mary', 'had', 'a', 'little', 'lamb'] def list(L): del L[3] L[3] = 'ram' print(list(list))

a.) ['Mary', 'had', 'a', 'lamb'] b.) ['Mary', 'had', 'a', 'little', 'lamb'] c.) the snippet is erroneous d.) ['Mary', 'had', 'a', 'ram']

17. What is the output of the following snippet?

def fun(x,y,z): return x+2*y+3*z print(fun(0,z=1,y=3)) a.) 0 b.) 9 c.) 3 d.) the snippet is erroneous

a.) the snippet is erroneous b.) 4 c.) 2 d.) 6

19. What is the output of the following snippet?

dct = { 'one':'two', 'three':'one', 'two':'three' } v = dct['one'] for k in range(len(dct)): v = dct[v] print(v)

a.) two b.) three c.) one d.) ('one', 'two', 'three')

20. What is the output of the following snippet?

tup = (1, 2, 4, 8) tup = tup[1:-1] tup = tup[0] print(tup)

a.) the snippet is erroneous b.) 2 c.) (2) d.) (2,)
