``````def max_lines(*file_names):

return max_name``````

# Get Filename with Max Lines

Write a function that receives one or many file paths as parameters and returns
the name of the file with max amount of lines.

Example:

``````max_lines('file1.txt', 'file2.txt')  # 'file1.txt
max_lines('file1.txt')  # 'file1.txt
max_lines('file1.txt', 'file2.txt', 'file3.txt)  # 'file3.txt
``````

### Test Cases

test one file -

``````import tempfile

def test_one_file():
fp = tempfile.NamedTemporaryFile(mode="w")
fp.write('this is line 1\n')
fp.write('this is line 2\n')
fp.write('this is line 3\n')
fp.flush()

assert max_lines(fp.name) == fp.name

fp.close()
``````

test two files -

``````import tempfile

def test_two_files():
fp1 = tempfile.NamedTemporaryFile(mode="w")
fp1.write('this is line 1\n')
fp1.write('this is line 2\n')
fp1.write('this is line 3\n')
fp1.flush()
fp2 = tempfile.NamedTemporaryFile(mode="w")
fp2.write('this is line 1\n')
fp2.write('this is line 2\n')
fp2.write('this is line 3\n')
fp2.write('this is line 4\n')
fp2.flush()

assert max_lines(fp1.name, fp2.name) == fp2.name

fp1.close()
fp2.close()``````
