Question

This is a time critical bug otherwise I wouldn’t have posted here and it’s also my very first try with django and python so consider accordingly .

I am getting error

%o format: a number is required, not str

in my django app . The place where it shows error :(I am trying to create a message string)

msg_donor = 'Dear %s,\nThank you for contributing to %s \'s fundraising campaign 
on Milaap.org. You\'ve made our day.\nRemember, since this is a loan, and not 
donation, 100% of your money will come back to you!\nYou will shortly receive 
your milaap login details. You can check who your money has gone to and track 
your repayments through your account. Be sure to sign up and check your account
regularly for updates.\n\n%s' % (d.name, c.fundraiser_name, regardsStr)

I haven’t written any %o in my application andI am wondering how this error can be produced ??

Answer 1

You have 100% of your money in your string. % is a formatting character. Use 100%% of your money to put a literal % in there.

(I’m sort of surprised that Python skipped over the space between % and o, but whatever.)
