1) Write a function named read_file() that reads the content of a text file (similar to the one generated by the take-input() function in 1.) and store all information in some suitable data structures (e.g., lists, dictionaries, sets, tuples, objects) of your choice. Yes, as the programmer you have the freedom to choose the data structure(s) that you want to use in this section. You can use multiple data structures if you wish. For example, I might want to use a tuple to store the names of the owner and the company as (Bond, Mart 007), and a 2D-list to store the product names/unit prices/stock quantities in this format, [ [prod1,prod2,prod3], [price1,price2,price3], [stock1,stock2,stock3] ]. Note, this is just an example and you can choose to store these data using a different format/data structure. Your function must use exception handling to handle all possible run-time errors so this function does not crash.
Hi! Please help me add this function to my python program. Code given below:
1) Write a function named read_file() that reads the content of a text file (similar to the one generated by the take-input() function in 1.) and store all information in some suitable data structures (e.g., lists, dictionaries, sets, tuples, objects) of your choice.

For example, I might want to use a tuple to store the names of the owner and the company as (Bond, Mart 007), and a 2D-list to store the product names/unit prices/stock quantities in this format,
[ [prod1,prod2,prod3], [price1,price2,price3], [stock1,stock2,stock3] ].
Note, this is just an example and you can choose to store these data using a different format/data
structure. Your function must use exception handling to handle all possible run-time errors so
this function does not crash.
MY EXISTING CODE:
def take_input(file1):
name=input('Please enter your name >>')
c_name=input('Hi {},please enter your company name >>'.format(name))
print("Let's set up a sales menu for {}".format(c_name))
file1.write(name)
file1.write(",")
file1.write(c_name)
file1.write("\n")
for i in range(1,4):
n=input("Enter item {}'s name >>".format(i))
file1.write(n)
try:
p=float(input("Enter item {}'s unit price >>".format(i)))
if(p<0):
p=float(input('Price must be positive. Please enter again >>'))
except ValueError :
p=float(input('Price must be a number. Please enter again >>') )
file1.write(",")
file1.write(str(p))
file1.write(",")
try:
q=int(input("Enter item {}'s quantity >>".format(i)))
if(int(q)<0):
q=int(input('Price must be positive. Please enter again >'))
except ValueError :
q=int(input('Price must be a number. Please enter again >>'))
file1.write(str(q))
file1.write("\n")
file1.close()
file1 = open('myfile.txt', 'w')
take_input(file1)
