Two ways:
- Reading the file manually. I recommend this because it's easy in 
this case and can help you developing the Python skills you want.

params = open("foo.txt","rt")
output = open("bar.txt","wt")
for line in params:
     x, y = line.split('\t')
     y = float(y) # make sure it's a number
     output.write("%s IRM=3PL IPB=%f\n" % (x, y))
output.close()
params.close()

- Using the standard csv module:

import csv
params = csv.reader(open("foo.txt", "r"), delimiter='\t')
output = open("bar.txt","wt")
for row in params:
     output.write("%s IRM=3PL IPB=%s\n" % (row[0], row[1]))
output.close()
params.close()
