in python in the simplest way
I have a file “a.txt” under the directory /temp/, the file contains some company names, the format is like that:
IBM
APPLE
cisco
Microsoft ……
Each line contains only one company name. Among these company names, some are capitalized such as IBM, APPLE, some are not, such as cisco. Write a program to read this file a.txt and convert all names to uppercase and save them to the file name “b.txt” in the same directory, and make sure they are SORTED in alphabetical order. For the example of companies above, the result file b.txt should look like:
APPLE
CISCO
IBM
MICROSOFT
Code:
#opening a.txt in read mode
f = open("temp/a.txt", "r")
#opening b.txt in write mode
fp = open("temp/b.txt","w")
#reading lines and storing in an list
list1 = f.read().split("\n")
list2 = []
#changing list items to uppercase using .upper()
for i in list1:
list2.append(i.upper())
#writing the items in list to b.txt as one company per line
#in alphabetical order
for j in sorted(list2):
fp.write(j)
fp.write("\n")
#closing the opened files
fp.close()
f.close()
#opening the file b.txt to read its contents
fp = open("temp/b.txt","r")
print(fp.read())
fp.cloae()
Screenshots
file a.txt
file b.txt
after compiling the outputs in the compiler and the b.txt are
OUTPUT
updated file
b.txt
Any queries comment please
Thank you:)

In Python and in one file please. (Simple functions with an expressions) Create a function called load_inventory(filename). The filename argument in this case specifies the name of a file that contains all the inventory/product information for the store, including product names, descriptions, prices, and stock levels. This function should clear any information already in the product list (i.e., a fresh start) and then re-initialize the product list using the file specified by the filename argument. You can structure your file...
