Python file data position

The problem I am facing is that I need to find the position of a string

Code:

file = open('data.txt', 'r')

print file.read

data.txt contains "banana", "mango", "apple", "pear", "dragon fruit"

For example how do I find the position of the string "mango"?

Answer

You can find the position of the word within the file using index. Try the following:

with open('data.txt', 'r') as f:
      content = f.read()
      print content.index('mango')

This would return the index of the word if it exists or give an error if it doesn’t find the word within the file.
