how to replace the hardcoded path in python

Question

In the below code how to replace the hardcoded path? Is there any way to read the path from some config file?

import sys 
sys.path.append(r" ./build/lib.linux-x86_64-2.4")

Answer 1

You can read the path from shell:

path = raw_input( "Insert path: ") # It will display "Insert path and will return the string entered into variable 'path'

Or using a file:

f = fopen( "<filepath>", "r" ) #open the file in reading-mode
list_of_lines = f.readlines() # read all the lines and put them in a list
f.close() # closes the file
for i in range( len(list_of_lines ) ): #cleaning from newline characters
 list_of_line[i] = list_of_line[i].strip()

And now, int the list_of_lines list you'll have all the lines read from the files...For example, now you can:

for i in range(len(list_of_lines)):
 sys.path.append( list_of_lines[i] )

Hope it help :)

• jaysh: I tried path = raw_input( "Insert path: ") ,its working fine
• jaysh: But the other one flag an error NameError: name 'list _of_line' is not defined
• jaysh: A small mistake list_of_line should be replaced with list_of_lines :-) in above code 's' is missing

Answer 2

Instead of replacing you can do sys.path.insert(0, "./build/lib.linux-x86_64-2.4") which will give preference to that path.

Answer 3

Python has something called .pth files for this purpose.
