Buenas:
Tengo este código de Python 2.x. No me funciona en Visual Studio Community 2019 (https://visualstudio.microsoft.com/es/vs/) (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.
Hola!
Por lo que colocas, el código es python 2 y lo estás corriendo con python 3. La función print necesita paréntesis en py3. En py2 era omitible.
Saludos!
Lo he instalado ahora y lo he cambiado.

Me sale con otro error.
CitarCan't find a usable init.tcl in the following directories:
C:/Python27/lib/tcl8.5 {C:/Users/Meta/Documents/Visual Studio 2019/Projects/Python_consola_01/Python_consola_01/env1/lib/tcl8.5} {C:/Users/Meta/Documents/Visual Studio 2019/Projects/Python_consola_01/Python_consola_01/lib/tcl8.5} {C:/Users/Meta/Documents/Visual Studio 2019/Projects/Python_consola_01/Python_consola_01/env1/library} {C:/Users/Meta/Documents/Visual Studio 2019/Projects/Python_consola_01/Python_consola_01/library} {C:/Users/Meta/Documents/Visual Studio 2019/Projects/Python_consola_01/Python_consola_01/tcl8.5.15/library} {C:/Users/Meta/Documents/Visual Studio 2019/Projects/Python_consola_01/tcl8.5.15/library}
This probably means that Tcl wasn't installed properly.
Precisamente en la primera línea.
root = Tkinter.Tk()
si usas python 3 y el código es de 2.x pódes tratar de convertirlo, para eso trae 2to3 ,claro que no te salvará en todos los códigos, pero si tenés esa mala costumbre de copiar y no entender lo básico te puede ayudar. Tkinter con mayúsculas es para 2.x si mal no recuerdo, hace años que no lo uso, para importar en 3 es tkinter con minúsculas.

Ya funciona gracias a todos.
