I have .txt file that has 6 lines on it. 

Line 1 name 
Line 2 eamil address 
line 4 phone number 
line 5 sensor name 
line 6 link .

I want to read those 6 lines in python and forward an email to the email address listed in the second line. I have a script that does this . But I don't know how to do this from .txt file . Thanks.

  • Actually, in retrospect, "Too Broad" is probably a better close reason, as this question asks how to do multiple things. – jpmc26 Feb 10 '17 at 18:51

with open("filename", "r") as f:
    for l in f:
      // do your processing, maybe keep track of how many lines you see since you need to do something different on each line

You said email lies in the second line of the file?

you can manipulate txt files by line using the readline() function.

usage example:

text file:

John Smith
john@smith.tld
line3
1-800-smth-here
sensorname
link

file = open(“testfile.txt”, “r”) 
client_email = file.readline(1)
print client_email

would result in 

john@smith.tld

  • Thanks , but it only reads the first two letters from the first line not the second line when I put :client_email = file.readline(2) – Ahmed Albadwi Feb 10 '17 at 22:06

Have a look at this question: How do I read a text file into a string variable in Python

It shows you how to read a file line per line into an array.

So you can do:

with open('data.txt', 'r') as myfile:
     data=myfile.read().replace('\n', '')

data[1] would then be the email address.

Please do proper research before asking.

  • I thought it was a borderline-duplicate as he added a little new aspect of assigning it to a variable, but you are right. – rudib Feb 10 '17 at 18:46
