Actually, I made another small adjustment to only get the distinct values. Thanks again. 

distinct_value = []

with open ("MDMALL.txt",) as myfile:
    with open ("MDMADJUST.txt",'w') as newfile:
        for lines in myfile:
                      if lines.startswith("TXA") and lines.split("|")[5] not in distinct_value:
                                distinct_value.append(lines.split("|")[5])
                                newfile.writelines(lines.split("|")[5])
                                newfile.writelines('\n')
                                
                                
print(*distinct_value, sep = '\n', end = '')

Funce -  Thank you. This is just what I needed. Worked like a charm. 

distinct_value = []

with open ("MDMALL.txt",) as myfile:
    with open ("MDMADJUST.txt") as newfile:
        for lines in myfile:
                      if lines.startswith("TXA"):
                                distinct_value = lines.split("|")
                                print(distinct_value[5])

Using Python3- I am trying to read a file line by line and extract the distinct values between the 2nd and 3rd pipe ( | ) on all lines that start with a certain string (in this example, "TXA"). I know how to open and read the txt files line by line, and also know how to write to a new one. Not sure how to only write the values between the 2nd and 3rd pipe. The pipes are not always in the same spot, so I cant use a set index to print. Example of txt file and code are below.  Any help will be appreciated. 

distinct_value = []

with open ("textfile.txt",) as myfile:
    with open ('newtextfile.txt','w') as newfile:
        for lines in myfile:
                      if lines.startswith("TXA") and lines not in distinct_value:
                                distinct.append(lines)
                                newfile.writelines('\n'+lines)

textfile.txt example below.

ABC|asdf|111|111
TXA|SS2|234|222
TTT|SS3|1113|456|
TXA|SS45|3455|1111
PCS|222|45|SP333
TXA|344|34|3334
TXA|34445|3455|143111

newtextfile.txt would have the following values

234

3455

34
