Question

please type code in Python

find all the VALID email address in this input text file and store them as a single column of valid email addresses in an output text file labeled OutputFile

First cut/paste the block of text below into a separate text file and label that data file InputFile:

FinancialAid Email: finaid@myschool.edu
Scholarships Financial Aid Phone: 979-555-3236
Email: random@ubx.net Financial visit@tamu.com Aid
helpdesk@tamu.notvalid Help Desk Central
fakename@egr.msu.org Dean's Office     
Jill Educational Program Coordinator II   

Create a program will find all the email address in InputFile and put into an output data file that you will label as OutputFile
Hint: use the character "@" as a cue to help find all the potential email addresses and then
see if you see an ".edu" or a ".net" or a...etc

You will want to check for valid email addresses ie ending in a valid extension. If you find the @ but when you test the rest of the candidate email, you don't see a valid extension simply flag it as an "ERROR" as shown in the output you should get:

scholarships@myschool.edu
financialaid@myschool.net
visit@tamu.com
ERROR=helpuodesk@tamu.notvalid
fakename@egr.msu.org

Answer 1

Code

f = open('inputFile.txt')
fo = open("outputFile.txt", "w")
line = f.readline()
while line:
extension=["edu","net","org","com","msv"]
lines=line.split(" ")
for word in lines:
if '@' in word:
dot=word.find(".")
if(dot>0):
ext=word[dot+1:]
while(True):
dot=ext.find(".")
if(dot>0):
ext=ext[dot+1:]
else:
break
ext=ext.rstrip()
if ext in extension:
word=word.rstrip()
fo.write(word+"\n")
else:
fo.write("Error"+word+"\n")
else:
fo.write("Error "+word+"\n")
line = f.readline()
f.close()
fo.close()

One possible solution would be to use regular expressions to search for patterns that match email addresses. Here is an example of how to do this using Python:

pythonCopy codeimport re# Open the input file and read its contentswith open('InputFile.txt', 'r') as f:
    input_text = f.read()# Define a regular expression pattern to match email addressespattern = r'\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b'# Find all the matches in the input textmatches = re.findall(pattern, input_text)# Filter out any invalid email addressesvalid_emails = [email for email in matches if email.endswith(('.com', '.edu', '.net', '.org'))]# Write the valid email addresses to the output filewith open('OutputFile.txt', 'w') as f:
    f.write('\n'.join(valid_emails))

This code reads the input file into a string, defines a regular expression pattern to match email addresses, and uses the re.findall() function to find all the matches in the input text. It then filters out any invalid email addresses by checking that the email address ends with a valid extension (.com, .edu, .net, or .org). Finally, it writes the valid email addresses to the output file.
