Writing for, while loops is useful when programming but not particularly easy when working interactively on the command line. There are some functions which implement looping to make life easier lapply: Loop over a list and evaluate a function on each elementsapply: Same as lapply but try to s...
Alternatively, we can loop through the list using NumPy. First, initialize a list then convert it into a NumPy array using thenp.array()function. This allows us to use NumPy functions to work with the list. importnumpyasnp# Initialize a listcourses=["Python","Spark","pandas","Java"]pri...

The API is pretty simple, three functions are provided in theDNSResolverclass: query(host, type): Do a DNS resolution of the given type for the given hostname. It returns an instance ofasyncio.Future. The actual result of the DNS query is taken directly from pycares. As of version 1.0....
