Python Enumerate Function - Learn how to use the enumerate function in Python to simplify your coding with effective indexing and iteration techniques.
This is because you use the yield keyword to send values back to the caller.Finally, you create two lists from my_enumerate(), one in which the start value is left as the default, 0, and one in which start is changed to 1. In both cases, you end up with a list of tuples in ...
If you'd like to read more about the usage of the yield keyword here, read our Guide to Understanding Python's "yield" Keyword! If you were to use the our_enumerate() function instead of the built-in one, we'd have much the same results: some_list = ['Looping', 'with', 'counte...
Again and again,and to the end 今天遇到一个新的函数 enumerate(), 可以从一个可迭代对象(dict,list,string 等)同时得到索引和值,这样就避免了另外生成变量来操作了 >>> l = ["hello","this","is","my","name"]>>>forindex,valueinenumerate(l):... print(index,value) ...
