You are not calling the function you defined. The name and number of
parameters are both wrong. To match your function definition, your
assignment should be:
>>> l = dbping.db_alive()
Note, also, that the "pass" statement in dbping.db_alive will cause a
syntax error. "pass" is only used when a code block is required but has
no executable statements. For example:
>>> intval = 0
.
.
.
try:
intval = int(strval)
except ValueError:
pass
# strval is not a valid string representation of an integer.
# intval remains 0.
# Suppress the error and continue the program.
