Reading in multiple files in Python and renaming them using string - str(i+1) not working?

I have the following loop, where cfile has been defined as 'C_' previously.

for i in range(15,25): infile = cfile + str(i+1) + '.txt' C + str(i+1) = np.loadtxt (infile,delimiter=',')

I have many files in the working directory named C_1, C_2, etc. I'd like to import these files into Python and name them as C_1, C_2, etc, but I'd only like to do so for that certain range. I am not understanding why the str(i+1) will not work.
