% Example latex source file for an edX course.
% This file can be compiled using
%
% python latex2edx example1.tex
%
% to generate all the content files for an example edX course named
% "1.00x". The files are saved in a subdirectory named "1.00x", and
% include:
%
% 1.00x/course.xml - main table of contents for course
% 1.00x/problems/Problem_1.xml - problem 1 (symbolic response example)
% 1.00x/problems/Problem_2.xml - problem 2 (option response example)

\begin{edXsection}{Introduction}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{edXproblem}{Problem 1}{40}
\section{Example of symbolic response}
This is a sample problem, which is worth 40 points. What is the number made famous by
Hitchhiker's guide to the galaxy?
\edXabox{type='symbolic' size='90' expect='42' }
\end{edXproblem}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{edXproblem}{Problem 2}{10}
\section{Example of option response}
This is a sample problem, which is worth 10 points.
Give the correct python {\tt type} for the following expressions. Select {\tt noneType} if the expression is illegal.
\begin{itemize}
\item {\tt 3} \edXabox{expect="int" options="noneType","int","float"}
\item {\tt 5.2} \edXabox{expect="float" options="noneType","int","float"}
\item {\tt 3/2} \edXabox{expect="int" options="noneType","int","float"}
\item {\tt 1+[]} \edXabox{expect="noneType" options="noneType","int","float"}
\end{itemize}
\end{edXproblem}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{edXproblem}{Problem 3}{10}
\section{Example of string response}
What state is Detroit in?
\edXabox{expect="Michigan" type="string"}
\end{edXproblem}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{edXproblem}{Problem 3.5}{10}
\section{Example of numerical response}
What is the numerical value of $pi$?
\edXabox{expect="3.14159" type="numerical" tolerance='0.01' }
\end{edXproblem}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{edXproblem}{Problem 4}{10}
\section{Example of custom response}
This problem demonstrates the use of a custom python script used for
checking the answer.
\begin{edXscript}
def sumtest(expect,ans):
(a1,a2) = map(float,eval(ans))
return (a1+a2)==10
\end{edXscript}
Enter a python list of two numbers which sum to 10:
\edXabox{expect="[1,9]" type="custom" cfn="sumtest"}
\end{edXproblem}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{edXproblem}{Problem 4}{10}
\section{Example of external response (coding problem)}
This problem demonstrates a python coding problem.
\begin{edXscript}
initial_display = ""
answer = """
print "hello world"
"""
preamble = """
code = '''
"""
test_program = """
'''
code = code.replace('print ','print >> LOG_OUTPUT, ')
exec(code)
"""
\end{edXscript}
Write python code which prints out ``hello world''
\edXabox{type="external" tests="1"}
\end{edXproblem}
