Questions’ generators

Implementation of the different kinds of questions’ generators.

In order to avoid tqdm’s experimental warning

warnings.filterwarnings("ignore", message='Using `tqdm.autonotebook.tqdm` in notebook mode')

Text with formulas and wildcards

A class to contain text that might include wildcards (“!”) and \(\LaTeX\) formulas. It is ultimately a wrapper around Python’s string.Template.

TemplatedLatexText

 TemplatedLatexText (raw_text:str)

Initialize self. See help(type(self)) for accurate signature.

t = TemplatedLatexText('''Compute the probability of error when !element_transmitted is transmitted and the power of thermal noise is $\frac{N_0}{2}=!noise_variance$.''')

Just evaluating the object shows the un-filled text

t

un-filled template:
Compute the probability of error when $element_transmitted is transmitted and the power of thermal noise is $$
rac{N_0}{2}=$noise_variance$$.

t.is_full

False

Calling the final property without properly filling the wildcards raises an error

# t.final

After filling the slots,

t.fill(element_transmitted='A', noise_variance='2')

calling final is fine

t.final

'Compute the probability of error when A is transmitted and the power of thermal noise is $\x0crac{N_0}{2}=2$.'

t.is_full

True

In such a case, evaluating the object returns the same thing (the final text)

t

Compute the probability of error when A is transmitted and the power of thermal noise is $
rac{N_0}{2}=2$.

If the wrapped text does not contain any wildcard, !, then there is no need to call fill to get the final text.

t = TemplatedLatexText('foo foo $A$')

t.is_full

True

t

foo foo $A$
