If I'm use this version of code: open(test.bin,b) - why test say me "error"? Atribute "r" was set by default or not?

Answer 1

hi, you have to set your b in ' ' like 'b'

Answer 2

if you want read the bin file ues 'rb' for write 'wb' i donr know if the read as default set. its better to wirte this. i think with only b the function dont know what read or write.

Answer 3

you forgot the " ' " like it should be written as 'b'
