Buenas:

Tengo este código de Python 2.x. No me funciona en Visual Studio Community 2019 (Gratuito).

import os, sys, tkFileDialog,Tkinter
 
root = Tkinter.Tk()
root.withdraw()
 
formats = [ ('Roms Super Nintendo SMC','.smc'),('Roms Super Nintendo SFC','.sfc'),('Fichier Bin','.bin'),('Roms Super Nintendo','.smc .sfc .bin') ]
 
input = tkFileDialog.askopenfile(parent=root,mode='rb',filetypes=formats,title='Select file to swap bin HI to LO like A16->A15, A17->A16...A21->A20 and A15->21')
if not input:
        print "Error: Cannot open file"
        sys.exit()
 
output = tkFileDialog.asksaveasfile(parent=root,mode='wb',filetypes=formats,title='Create output file name')
if not output:
        print "Error: cannot create output file"
        sys.exit()
 
 
# reading input file to a byte array
data = bytearray(input.read())
 
# calculating rom size in 2 exponants
expsize = 0
bytesize = len(data)
while bytesize > 1:
        expsize += 1
        bytesize = bytesize // 2
 
# init a proper size empty bytearray
buffer = bytearray()
for i in range(2**expsize): buffer.append(0)
 
# let's do the swap	
count = 0	
for i in range(len(data)):
        addr = (i & 0x7fff) + ((i & 0x008000) << (expsize - 16)) + ((i & 0x010000) >> 1) + ((i & 0x020000) >> 1) + ((i & 0x040000) >> 1) + ((i & 0x080000) >> 1) +	((i & 0x100000) >> 1) + ((i & 0x200000) >> 1)
        if addr != i: count += 1
        buffer[addr] = data[i]
print "Swapped %s (%s) addresses" % (count, hex(count))
 
# writing output file
output.write(buffer)
 
# close file handles
input.close()
output.close()

Me sale estos errores.

SyntaxError: Missing parentheses in call to 'print'. Did you mean print("Error: Cannot open file")?
Press any key to continue . . .

¿Les dicen algo?

Saludos.

Lo he instalado ahora y lo he cambiado.



Me sale con otro error.


Precisamente en la primera línea.
