I am trying to generate a list of examples using PythonTeX and pgffor but this doesn't seem to work ?! The same example is repeated 5 times instead of getting 20 different examples. What's wrong in the MWE below ? Thank you.
\documentclass[12pt]{article}
\usepackage{amsmath, pgffor}
\usepackage{pythontex}
\pagestyle{empty}
\begin{document}
\begin{pycode}
import random
def gcd(a,b):
if(b==0):
return a
else:
return gcd(b,a%b)
c = random.randint(400,1000)
d = random.randint(50,400)
p = gcd(c,d)
\end{pycode}
\foreach \n in {1,2,...,20}{
The greatest common divisor of $\py{c}$ and $\py{d}$ is
\hfill $\gcd\left( \py{c};\py{d} \right) = \py{p}$
}
\end{document}
edit : Thanks to @user187803, the number of iterations is now ok, but I am always getting the same example.
Best Answer
To get 20 iterations, you have to replace
1,2,,..,20
with1,2,...,20
. You already did that in your edit.You only draw random numbers for
c
andd
once, so you cannot expect to get 20 different results. You need to draw new values in every iteration, e.g.
