viz.input

[new_horizon]

Hi All,

I am trying to enter some code that will allow the experimenter to enter a filename for the test subject - I would like this file name to be the participant number, however, when I input 01 or 02 etc, the program does not run.

Is there a specific command for allowing number entry? I assume the command below only takes care of string?

filename = viz.input('What filename for dataout?')

Thanks

You can manually convert the string to an integer. Example:
strValue = viz.input('Enter a number:')
try:
intValue = int(strValue)
print intValue
except ValueError:
print 'You did not enter a valid number'

Thanks for the reply.

Am I correct in saying however, that you cannot combine an integer and a string to make a file name?

For example if choiceM[selectM] is a string and filename is an integer?

filename = filename + choiceM[selectM]

Thanks

Yes, just convert the integer to a string and then you can concatenate it with another string:
filename = str(filename) + choiceM[selectM]
