Question

I have the following code which works and gives me each value. I can’t seem to create a list of all the values once they are collected. I’m currently getting one value at a time..! I’ve tried the two following ways:

def numberwritten(self, event, key, index):
    self.values = []
    if not self.left[index]:
        self.box[key].config(fg='black')
        self.left[index] = True
        self.values.append(self.box[key].get())
        print self.values

This works with just one value being printed each time but I would like a list I can assign ‘n’ variables to (the number of values obtained changes at random each time).

I would like to do for example ‘Value %s” % i = value obtained.

Answer 1

self.values = [] is clearing the list each time you call numberwritten() so that is why you are printing just one value. Declare self.values globally or in the __init__() function in your class.

In terms of formatting for printing one value during each loop iteration, try something like this:

print("Value %i = %s" % (index, self.box[key].get())

Edit: I borrowed the following from this answer if you actually want to print your entire list each loop iteration:

# Map items in self.values to strings (necessary if they are not strings).
print("All values: [%s]" % ", ".join(map(str, self.values)))

# Use this if the contents of self.values are strings.
print("All values: [%s]" % ", ".join(self.values))
