Best way to retrieve variable values from a text file?

Question

Referring on this question, I have a similar -but not the same- problem..

On my way, I\'ll have some text file, structured like:

var_a: \'home\'
var_         


        

Answer 1

Suppose that you have a file Called "test.txt" with:

a=1.251
b=2.65415
c=3.54
d=549.5645
e=4684.65489

And you want to find a variable (a,b,c,d or e):

ffile=open('test.txt','r').read()

variable=raw_input('Wich is the variable you are looking for?\n')

ini=ffile.find(variable)+(len(variable)+1)
rest=ffile[ini:]
search_enter=rest.find('\n')
number=float(rest[:search_enter])

print "value:",number
