python return key whose value is

Comment

# Basic syntax
list(your_dict.keys())[list(your_dict.values()).index("value")]
# Where:
#	- list(your_dict.keys()) gets all keys from the dictionary and converts them
#		to a subscriptable list
#	- list(your_dict.values()) gets all values from the dictionary (in the same
#		order as the keys) and converts them to a list
#	- .index("value") returns the index of the first element that matches "value"
#		if any. This is then used to return the corresponding key from the list
#		of keys
# Note:
#	- This approach only returns the key for the first matching value
#	- See source for options with better performance

# Example usage
# Say you have the following dictionary and want the key whose value is 11
your_dict = {"Java":100, "Python":112, "C":11}
 
# You could get this with:
list(your_dict.keys())[list(your_dict.values()).index(11)]
--> "C"
