I agree, was just trying to take home the point that if at all a format string must be used (for whatever obscure reason), then it is not necesssary to know beforehand the number of values in the dictionary (or the length of list of its values) in order to to build the format string. Hope that was

[Tutor] Decimal Conversion

Hi, I'm new to Python, and found some problems on the internet that would be a good start to begin. The problem I have is that my conversion program (which currently only converts unsigned integers) also prints all these brackets and commas. Here is my code and the result: CODE: print "" print "--

After sending the last email, I was more and more unsatisfied with it's level of detail I provided. Your original statement: b=b,r was doing nothing like you intended. The comma operator in this instance is making a tuple. The name b was being reassigned to the new tuple created by the comma ope

However since r is an int and b is a string, you will get an error when you try and concatenate them. >>> b='' >>> b+=1 Traceback (most recent call last): File "", line 1, in TypeError: cannot concatenate 'str' and 'int' objects So you need to convert r to a string before you assign it to b >>
