How to write the results of functions to a separate python text file?

Question

Python

There are working functions, but how to make sure that all the results from these functions are written to a separate text file at the output?
I tried to write my own code - it does not work:

def write():
    fy = input("Введите имя файла для сохранения")
    file2 = open (fy, "w")
    file2.write (max_sh(), count())
    file2.close()
print (write())
