You can write directly to the Python script using "fprintf":

 replaceLine = 2
 fid = fopen('mypyfile.py', 'r+');
 for k=1:(replaceLine-1);
     fgetl(fid);
 end
 fseek(fid, 0, 'cof');
 fprintf(fid,'print("%s")','myMAT.mat')
 fclose(fid)

Refer to the following link for additional information on writing data to text files:

Consider writing the MAT file location to an intermediate medium (such as a text file or database) in MATLAB and reading from that medium in Python.

fgetl(fid) is not taking me to the correct line to be replaced. It seems fgetl(fid) is also reading space in between. How to remove this spaces and just read the lines. This is the output I am getting eg:

tline =

file1

tline =

''

tline =

file2

tline =

''
