python implementation: remove spaces and line breaks, differences compare two text files text content, and outputting a difference value

Coding #: utf-8 
# preparation, the generated file transfer by t2.text to Notepad ++ utf-8 encoded 
# result is output as a first difference data existence 
# modify every time a new file requires t2.text transcoding 
os Import 
os.chdir ( "D: / tesseract / T2") to change the file directory # 
# os.system ( "dir") 
#python 3.x 
#python compare the contents of two files

    FA = file1.read () 
    FB = file2.read () 
    FA = fa.replace ( "", "") 
    FA = fa.replace ( "\ n-", "")

Note: in the above code, Python points although the global and local variables, but for the if statement and, within the scope thereof and an outer scope is the same scope, for the variable which is the reason the flag can be used if the
