How to print a dictionary's key?

Question

I would like to print a specific Python dictionary key:

mydic = {}
mydic[\'key_name\'] = \'value_name\'

Now I can check if mydic.has_

Answer 1

If you want to get the key of a single value, the following would help:

def get_key(b): # the value is passed to the function
    for k, v in mydic.items():
        if v.lower() == b.lower():
            return k

In pythonic way:

c = next((x for x, y in mydic.items() if y.lower() == b.lower()), \
     "Enter a valid 'Value'")
print(c)
