Time Complexity:The enumerate() function has a time complexity of O(n). ‘n’ is the number of elements in the sequence. It means that in order to generate the index-element pairs, enumerate() has to iterate through the entire sequence. As a result, when dealing with long sequences, t...
What Is Enumerate in Python? Before we jump into understanding What is enumerate in Python, let us unfold the chapter by finding out what enumerate Python is and what it means to enumerate something. The term ‘enumerate’ is commonly used in mathematics and computer science, which is nothing...
fori, item inenumerate(items): 除此之外,enumerate还支持传入参数。比如在某些场景当中,我们希望下标从1开始,而不再是0开始,我们可以额外多传入一个参数实现这点: fori, item inenumerate(items,1): 循环是我们编程的时候必不可少的操作,也正因此,enumerate函数使用非常广泛。但是有一点需要注意,如果我们迭代的...
Python >>>forcount,(one,two,three)inenumerate(zip(first,second,third)):...print(count,one,two,three)...0 a d g1 b e h2 c f i In theforloop in this example, you nestzip()insideenumerate(). This means that each time theforloop iterates,enumerate()yields a tuple with the first...

So as you know, indices in python start at 0. This means that when you use the enumerate function, the index returned for the first item will be 0. However, in some cases, you want the loop counter to start at a different number. enumerate allows you to do that through an optional ...
