Add line numbers and more characters to lines in file

Any help is hugely appreciated. I'm trying to take a file that has a list of lines formatted like the sample below, remove the line break and any space at the end of the line and add a line number.

This: 

9010
9011 
9012

Needs to become this: 

9010='0';9011=1';9012='2';

I've gotten pretty far but can't get it to remove the white spaces at the end of each number and can't get it to add the other characters. Here's my code: 

f = open("datesfile.txt", "r")
lines = f.readlines()
lines =[each.replace('\n', '') for each in lines]
lines =[each.strip(' ') for each in lines]
f.close()
outtext = ["%s" + "=" + "\'" + "%s" + "\'" + ";" % (line,i) for i, line in enumerate(lines)]
outfile = open("variablerecord.txt","w")
outfile.writelines(str("".join(outtext)))
outfile.close()

But here's the error I get: 

  File "recodevariableforR.py", line 8, in <module>
    outtext = ["%s" + "=" + "\'" + "%s" + "\'" + ";" % (line,i) for i, line in enumerate(lines)]
TypeError: not all arguments converted during string formatting

Why wouldn't all arguments convert? Is there a simpler way to do this?

The output line i.e. line 8 should be

outtext = ["%s = '%s';" % (line,i) for i, line in enumerate(lines)]
