Assuming that you have H matrix and Z matrix stored as NumPy arrays, you can generate an alist file using the following Python code:
```python
import numpy as np
# load H matrix and Z matrix
H = np.load('H.npy')
Z = np.load('Z.npy')
# get number of variables and clauses
n_vars = H.shape[1]
n_clauses = H.shape[0]
# initialize alist file content
content = f'p cnf {n_vars} {n_clauses}\n'
# iterate over clauses
for i in range(n_clauses):
clause = []
# iterate over variables in clause
for j in range(n_vars):
# if variable is in positive polarity
if H[i, j] == 1:
clause.append(j + 1)
# if variable is in negative polarity
elif H[i, j] == -1:
clause.append(-(j + 1))
# add Z variable to the end of clause
clause.append(n_vars + i + 1)
# convert clause to string and add to content
content += ' '.join(str(x) for x in clause) + ' 0\n'
# write content to alist file
with open('output.alist', 'w') as f:
f.write(content)
```
This code creates an alist file called "output.alist" in the current directory, which contains the problem in CNF form represented by the H matrix and Z matrix.
