No matter what's the value of what, the true part of if condition is always executed.
what = ""
def sendPacket(where, what):
print("sendPacket()> i/p what :" + what)
if what:
zb.send('tx',dest_addr_long = where,dest_addr = UNKNOWN,data = what)
print('sendPacket()> Data: '+ what)
print('sendPacket()> Data sent to: '+ where )
else:
print('sendPacket()> data not sent')
I want the true part to be executed only when what is not equal to null or empty. Any help would be appreciated.
Ask explicitly for the condition you want:
if what and not what.isspace():
The above states that what is not null, is not an empty string, and is not a string of just whitespaces. It's possible that your input has some line break, tab, or other non-printable character that's messing with the test.
