Python Email Validation - Time Out Error - File Handling Issue

Question

I am using python module ( validate_email ).

from validate_email import validate_email

result=open('output.tsv','w')

f=open('input.csv','r')

y=[]

result.write('Email_address\tEmail_validation\n')

for i in f:
    y.append(i.replace('\n',''))

for j in range(len(y)):
    val=validate_email('%s'%y[j], verify=True)
    result.write('%s\t%s\n'%(y[j],val))
    print y[j],val

In that the input.csv file contains the list of email Id's to check.

After the for loop the result will be written in output file.

Problems:

1. Some time the script raise the Time out error raise TimeoutError, 'Timeout'

My input file contains 300 email Id's.

2. The output file was writing only the results of 120 emails. but on that time the program is still running upto 300 requests ( emails).

Answer 1

As an more optimized way instead of range(len(y)) you can just use y in your for loop : because that every indexing or len has O(n) order and you are using 3 indexing in the loop also you have len(y) too . Just use in operation :

for j in y:
    val=validate_email('%s'%j, verify=True)
    result.write('%s\t%s\n'%(j,val))
    print j,val
