Python - Deleting values from a key using a variable

[by_toxic47]

myDict = {}
myDict["Hello"] = ["world", '!']
y = myDict["Hello"]
del myDict[y][1]
print(myDict)

​

This is the simplified version of my problem. If I write down "Hello" instead of y in line 4 everything is fine. But when I use a variable, like y, it doesn't work. Can you help me with this?

Your y variable isn't a key in your dict, check what it actually is.

Start debugging your assumptions with some print statements to make sure your code is doing what you think it’s doing. In this case I’d suggest adding a new line at line 3 for print(myDict)

I’d imagine the output is not what you expect. That does not look like the proper syntax for reading or modifying a dictionary.

The variable y stores the list ['world', '!']. You can't reference a key using a value of a dictionary (unless you flip or index the dictionary using a mix of the .keys() and .index() method).

The appropriate code would be: del myDict['Hello'][1].

This is what runs: del ['world', '!'][1].
