Concatenation two files in python-CodePudding

I have the following functions to read files, then store them inside variables:

def browseFiles():
    filename = filedialog.askopenfilename(initialdir = "/home",
                                          title = "Select a File",
                                          filetypes = (("Text files",
                                                        "*.docx*"),
                                                       ("all files",
                                                        "*.*")))
    label_file_explorer.configure(text="File Opened: "  filename)
    with open(filename) as fp:
     firstfile = fp.read()

def browseFiles1():
    filename1 = filedialog.askopenfilename(initialdir = "/home",
                                          title = "Select a File",
                                          filetypes = (("Text files",
                                                        "*.docx*"),
                                                       ("all files",
                                                        "*.*")))
    label_file_explorer.configure(text="File Opened: "  filename1)
    with open(filename1) as fp:
     secondfile = fp.read()

I want to concatenate firstfile and secondfile together, then produce a third file. So, I used :

firstfile  = "\n"
firstfile  = secondfile
  
with open ('thirdfile.docx', 'w') as fp:
    fp.write(firstfile)

My questions is how to access the variables firstfile and secondfile in each function and use them to produce a third file ?

CodePudding user response：

You can return the file contents from the two functions, and that's how you'll access both from your "main function".

CodePudding user response：

you can use something like this

with open('<file1>') as f1, open('<file2>')  as f2, open('file3') as f3:
    # do the magic

CodePudding user response：

You have to return the firstfile and the secondfile from the 2 functions, store them in variables and then use the pd.concat function.

def browseFiles():
    filename = filedialog.askopenfilename(initialdir = "/home",
                                          title = "Select a File",
                                          filetypes = (("Text files",
                                                        "*.docx*"),
                                                       ("all files",
                                                        "*.*")))
    label_file_explorer.configure(text="File Opened: "  filename)
    with open(filename) as fp:
     firstfile = fp.read()

    return firstfile


def browseFiles1():
    filename1 = filedialog.askopenfilename(initialdir = "/home",
                                          title = "Select a File",
                                          filetypes = (("Text files",
                                                        "*.docx*"),
                                                       ("all files",
                                                        "*.*")))
    label_file_explorer.configure(text="File Opened: "  filename1)
    with open(filename1) as fp:
     secondfile = fp.read()
    
    return secondfile

thirdfile = pd.concat([firstfile, secondfile])

Here is the link to the documentation of concat.

Cheers!
