Python用户输入文件名

Question

I'm trying to write a program that takes a users input for a file name, and then either opens the file to add to it, or prints what is already in the file, so far this is what I have: (I keep getting a syntax error where it tries to print 'file name' is now open) any ideas/tips?

            elif choice == 'a':
                print("You selected 'a', you can now add to your file.")
                print("File", ui "is now open.")

Answer 1

You are having the following print statement in your elif block

print("File", ui "is now open.")

which is syntactically wrong, since it doesn't have a comma after ui , and you can't concatenate or perform any other operation thus.

Either of the following should correct that

print("File", ui, "is now open.")
print("File %s is now open." % ui)

Answer 2

Another problem beyond the one you asked about:

r = open(ui, 'r')
print(r)
close.ui()

I assume this is meant to print the contents of the file named by ui . But what it will actually do is to print something like <open file 'filename', mode 'r' at 0x10d7556f0> , and then throw an exception once it hits close.ui() . r is the file object; you want to read it, and then close it -- both of these are methods of r :

r = open(ui, 'r')
print(r.read())
r.close()

Hmm, I see you edited this out of your question while I was typing. Hope it helps anyway.
