You're right...how strange. Here's the whole code:
tables = []
bst = []
bdt = []
spt = []
sst = []
sstp = []
cursor.execute('show tables;')
all = cursor.fetchall()
for a in all:
tables.append(a[0])
for table in tables:
if table[0] == 'b': # This is a basic table
if table[1] == '0': # This is a basic static table
bst.append(table)
# elif table[1] == '1': # This is a basic dynamic table
# bdt.append(table)
# Basic dynamic tables, like "pic" below, have to be manually created.
elif table[0] == 's': # This is a store table
if table[1] == '0': # This is a store primary table
spt.append(table)
elif table[0] == 't': # This is a store subtype table
bits = string.split(table, '0')
sst.append(bits[2])
sstp.append(bits[1])
subtypes = dict(zip(sstp, sst))
print sst
print '<br />'
print sstp
print '<br />'
print subtypes
print '<br />'
This is what prints out:
['doctors', 'patient']
['prescriptions', 'prescriptions']
{'prescriptions': 'patient'}
TIA,
