Hi, My name is Dan and I'm a newb to python (and programming. Please
forgive)
I am trying to get a value from a nested dictionary. I would like to
pass in a parameter from a conf file, then compare it to a value in the
dictionary, and verify that it is a valid value. (The SSL_MODE Portion
of the below listed dictionary)
I have d1{key1: val1,
key2: val_2{key_a: val_a, key_b: val_b},
key3: val_3}
And In comes the value from the conf file key2: val_a
Any Ideas?
