How to escape Python name error in for loop calling Shell script?

Question

 def startdataprocessing (self, widget):
    text_file = open("SRAIdFromPythonInput.txt", "w")
for item in text_file:
    execute('bash ./oneclickdataprocessor.sh')
text_file.close()

I have error text_file is not defined. How to fix that? Is it correct to call .sh script over every item in .txt file or I should use Linux shell embedded for loops?

You're calling `text_file` which is a variable defined *within* `startdataprocessing` — jmk, Apr 19 '17 at 10:46
Your `for item` loop is **useless**, as you don't pass `item` to your `execute(...`. — stovfl, Apr 19 '17 at 10:49
What is the `execute()` function? It's not a standard Python built-in. — martineau, Apr 19 '17 at 11:23

In terms of your script

text_file = open("SRAIdFromPythonInput.txt", "w")
for item in text_file:
    execute('bash ./oneclickdataprocessor.sh')
text_file.close()

For calling external shell files consider the subprocess module. More in this question
