Question

convert this code to accept int value instead of float values using python. Make sure to follow the same code. do not change the steps and make sure to point to what code you replaced. make sure to have 2 files

Method:-----------------------

#define a python user difined method

def get_float_val (prompt):

is_num = False

str_val = input (prompt) #prming read for our while

#while is_num == False: (ignore this but it works) old school

while not is_num:

try:

value = float(str_val)

is_num = True

except:

print (str_val + " is Not a float " )

str_val = input ( prompt )

#while

return value

#end get_float_val

#step 9 user defined method to test if a value is a float or not

def is_float (value):

try:

num = float(value)

return True # if we make it here, then the conversio was successful

except:

return False # conversion failed. It is not float

#end is_float

#step #15 find_string() method

# def means we are defining a method

# python does not have a return type

# 1st param list to search; 2nd param value to find

Method file:

def find_string(the_list, find_val):

list_len = len(the_list) #get the list size

found = False

i = 0

idx = -1 #where in the array was found; -1 = not found

#search the array for the value

while i < list_len and idx < 0: #equivelant to found == false

if find_val.upper() == the_list[i].upper():

idx = i

found = True

#end if

i += 1

#end while

return idx

#end find_string

#step 18

def find_int(the_list, find_val):

list_len = len(the_list) #get the list size

i = 0

idx = -1 #where is the array the value was found; -1 = not found

#search the array for the value

while i < list_len and idx < 0: #equivalent to found == false

if find_val == the_list[i]:

idx = i

#end if

i += 1

#end while

return idx

#end find_string

MethodTest: ------------------

import Method as m

def main():

#step 4 test our get_float_val() method

float_val = m.get_float_val( " Enter a floating point number: " )

print ( "Float value " +str( float_val ) + " was entered. ")

#step 10 test is_float()

str_val = input(" Enter a float value: ")

result = m.is_float( str_val )

#if result == True

if result:

print( str_val + " is a float " )

else:

print( str_val + " is not a float " )

#step #16 test find_string()

my_list = [ "goat", "zebra", "horse", "fox", "dog", "cat"]

value = input("Enter a value to find: ")

#call our method

index = m.find_string(my_list, value)

if index >= 0:

print ("Found " + value + " at index " + str(index) )

else:

print ( value + " NOT FOUND" )

  

#step #19 test find_int()

my_list = [3,5,7,9,11,13,15]

value = int(input( "Enter an integer to find: ") )

#call our method

index = m.find_int(my_list, value)

if index >= 0:

print( "Found " + str(value) + " at index " + str(index) )

else:

print( str(value) + " NOT FOUND!" )

#if this is the main module then execute main()

if __name__ == "__main__":

main()

The changes made are specified in the commentions of the code. Please follow them.

Method.py:

list_len = len(the_list) #get the list size
found = False
i = 0
idx = -1 #where in the array was found; -1 = not found
#search the array for the value
while i < list_len and idx < 0: #equivelant to found == false
if find_val.upper() == the_list[i].upper():
idx = i
found = True
#end if
i += 1
#end while
return idx
#end find_string
