How to search Python dictionary for matching key?
If you have the exact key you want to find, then you can simply use the [] operator or get the function to get the value associated with this key. For example,
Example
a = { 'foo': 45, 'bar': 22 } print(a['foo']) print(a.get('foo'))
Output
This will give the output:
45 45
Example
If you have a substring that you want to search in the dict, you can use substring search on the keys list and if you find it, use the value. For example,
a = { 'foo': 45, 'bar': 22 } for key in a.keys(): if key.find('oo') > -1: print(a[key])
Output
This will give the output
45
