[Tutor] a question about symbol
When I test the following code, I got something like (use 80 as argument): 80?F=27?C Why '?' appear? # code import string, sys # If no arguments were given, print a helpful message if len(sys.argv)==1: print 'Usage: celsius temp1 temp2 ...' sys.exit(0) # Loop over the arguments for i in sys.argv[1:]: try: fahrenheit=float(string.atoi(i)) except string.atoi_error: print repr(i), not a numeric value else: celsius=(fahrenheit-32)*5.0/9.0 print '%i\260F = %i\260C' % (int(fahrenheit), int(celsius+.5)) ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Hi Linda, Let's compare the output to what we think is producing it. The very last statement in the program looks like the thing we want to watch: print '%i\260F = %i\260C' % (int(fahrenheit), int(celsius+.5)) One thing that caught me off guard is the '\260' thing. Can you explain what that is for? ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] MySQLdb.converters.escape() type error
Hi, after upgrading to MySQL 5 and MySQLdb 1.2.1_p2, I have the following problem: self.db=MySQLdb.connect(host=host, user=user, passwd=passwd, db=db, cursorclass=MySQLdb.cursors.DictCursor) stringel = 'Some string' stringel = self.db.escape(stringel) File ./test.py, line 12, in ? stringel = self.db.escape(stringel) TypeError: no default type converter defined I checked the documentation for MySQLdb.converters and saw that the escape() function takes a dictionary as an obligatory second argument. This is odd, because I have always been using escape(string) without a problem. The changes in MySQLdb 1.2.1_p2 list: Mapped a lot of new 4.1 and 5.0 error codes to Python exceptions Could someone point me to the problem in the MySQL side?

I think it is the symbol put before F or C ( should be a small circle)...\I do not know why it appeared ? ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Hi Linda, Ok, let's restate the question then. The question really seems to be: How do I print a 'degree' symbol on the screen? Does that sound right to you? Unfortunately, this is not such a fun problem to solve. It really depends on our output device --- the terminal --- and the support that our output device gives us. Some terminal displays don't provide much graphical support at all. In this case, you're seeing a question mark because the terminal has no clue how to render the character we're trying to display. Other terminals accept and display Unicode or other extended character sets, but it sounds like yours may not. You may want to read The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) because it gives more background information on this ugly mess: http://www.joelonsoftware.com/articles/Unicode.html If it isn't too much of a deal for you, just change '\260' to 'degrees'. *grin* Best of wishes! ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

I paste it here 80F = 27C and I see degree symbols.
