Python wait time, wait for user input

input timer
· Have one thread get the input (which can block), but then put the info into a queue for the other thread to read. The other thread can timeout if the queue doesn’t give any information in the time. A perhaps simpler way is to loop over input, but then just check a timer for when the input arrived.

Readline Be careful when using readline().Do specify a timeout when opening the serial port otherwise it could block forever if no newline character is received. Also note that readlines() only works with a timeout.readlines() depends on having a timeout and interprets that as EOF (end of file).

@ChezCoder you can do something like this: import time start = time.time() # do your input thing end = time.time() taken = end-start # in seconds This works because time.time() gives the time in seconds since Jan 1 1970 00:00:00 (for some weird reason computers “start at that time”) so you can get the time before and after the input and it will give you the difference in time in seconds.
