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)
audit_log("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.
