For example, I don't think that supporting

float('١٢٣٤.٥٦') 1234.56

Even if this is somehow an accident or something that someone snuck in, I think it a good idea that users be able to input amounts with their native digits. That is different from requiring programmers to write literals with euro-ascii-digits

is more important than to assure users that once their program accepted some text as a number, they can assume that the text is ASCII.

Why would they assume the text is ASCII? def deposit(self, amountstr): self.balance += float(amountstr) auditlog("Deposited: " + amountstr)

If the programmer want to assure ascii, he can produce a string, possible formatted, from the amount

depform = "Deposited: ${:14.2f}".format def deposit(self, amountstr): amount = float(amountstr) self.balance += amount # audit_log("Deposited: " + str(amount) # simple version audit_log(depform(amount))

Given that amountstr could be something like ' 182.33 ', I think programmer should plan to format it.
