Let's identify the errors in each of the provided programs:

a)

def create (text, freq):
    for i in range (1, freq):
        print text

create(5) # function call

Error:

Missing parentheses in the

print

statement (Python 3).

Incorrect number of arguments passed to

create

.

Fix:

def create(text, freq):
    for i in range(1, freq):
        print(text)

create("Sample Text", 5)  # function call

b)

from math import sqrt, ceil

def calc():
    print cos(0)

calc() # function call

Error:

Missing import for

cos

function in

math

module.

Missing parentheses for

print

(Python 3).

Fix:

from math import sqrt, ceil, cos

def calc():
    print(cos(0))

calc()  # function call

c)

mynum = 9

def add9():
   mynum = mynum + 9

add9() # function call

Error:

mynum

inside the function is considered local, causing

UnboundLocalError

because it is being used before assignment.

Fix:

mynum = 9

def add9():
   global mynum
   mynum = mynum + 9

add9()  # function call

d)

def findValue(val1 = 1.1, val2, val3):
    final = (val2 + val3) / val1
    print(final)

findValue() # function call

Error:

Non-default arguments (

val2

,

val3

) cannot follow default arguments (

val1

).

Fix:

def findValue(val2, val3, val1=1.1):
    final = (val2 + val3) / val1
    print(final)

findValue(1, 2)  # function call

e)

def greet():
    return "Good morning"

greet() = message # function call

Error:

Incorrect assignment syntax.

greet()

returns a value, it cannot be assigned to.

Fix:

def greet():
    return "Good morning"

message = greet()  # function call
