和Golang中一样，Python中是否有空白标识符？ [重复]

Question

This question already has an answer here:

• What is the purpose of the single underscore “_” variable in Python? 4 answers

For instance, I have a string that splits into 3 parts but I need just the first and third parts.

one, two, three = '1 2 3'.split()

After the above line, I would have to execute a "del" to remove it from variable list.

del(two) 

Is there a way I can discard "two" immediately? Like"

one, _, three = '1 2 3'.split()

Additionally, this is not a question about language semantics which has been answered in the following question.

What is the purpose of the single underscore "_" variable in Python?

This is a question if Python runtime has that feature to remove the variable automatically.

Answer 1

If this is your actual case you can do one,_,three = '1 2 3'.split()

Whereas, an alternative would be one,three = '1 2 3'.split()[::2], which gives only odd numbers, or skips the odd-indexed values.

But for a high index, such as 20, the only way to skip that would be to delete the element from the list(I believe), or do one,two,three ... _, twenty
