When Cisco ACI was launched it promised to do everything you need (plus much more, and in multi-hypervisor environment). It was quickly obvious that you can’t do all that on ToR switches, and need control of the virtual switch (the real network edge) to get the job done.

The final exercise of week 4 is the following.
III. Create a program that converts the following uptime strings to a time in seconds.
uptime1 = 'twb-sf-881 uptime is 6 weeks, 4 days, 2 hours, 25 minutes'
uptime2 = '3750RJ uptime is 1 hour, 29 minutes'
uptime3 = 'CATS3560 uptime is 8 weeks, 4 days, 18 hours, 16 minutes'
uptime4 = 'rtr1 uptime is 5 years, 18 weeks, 8 hours, 23 minutes'
For each of these strings store the uptime in a dictionary using the device name as the key.
During this conversion process, you will have to convert strings to integers. For these string to integer conversions use try/except to catch any string to integer conversion exceptions.
For example:
int('5') works fine
int('5 years') generates a ValueError exception.
Print the dictionary to standard output.
The first step is to import pretty print which we will use to print the dictionary.
# Import pretty print import pprint
To do the conversion from years, weeks and days to seconds, we are going to need some constants. Constants are usually defined with the variable Continue reading
