To check if a Python Dictionary contains a specific key or not you can make use of the if statement with a in keyword,
Example:
# Python Dictionary containing
# names of cities
def check_for_key(cities,city_name):
if city_name in cities:
print("City {} is available in dictionary cities..".format(city_name))
else:
print("City {} is not available in dictionary cities..".format(city_name))
cities = {'Tokyo','Paris','New York', 'Mumbai', 'London'}
check_for_key(cities,'London')
check_for_key(cities,'Austin')
Output:
City London is available in dictionary cities..
City Austin is not available in dictionary cities..
