Use for loop to iterate through an iterable object such as alist,set,tuple,string,dictionary, etc., or a sequence. This iteration process is done in one-line code this is the basic way to write for loop in one line. Let’s implement a one-lineforloop to iterate over Python iterable ...
6. Iterate List using For Loop and Get Indexes in Backwards You can also get the loop index in backward directions using the range() function with a len() function. Let’s iterate over therange(len(list) -1, -1, -1)function to iterate the looping from the backward direction and get ...
#Method 2 - iterate through indexes: for i in range(len(list)): print list[i] 1. 2. 3. 4. 5. 6. list的用法 - 小例子1 - string也是一种list for letter in "Codecademy": print letter print print word = "Programming is fun!" for letter in word: # Only print out the letter i...
In the final loop, instead of going through every path, slice the list for the first ten items, and lastly, when printing use the path provided but query the dictionary again for the size value of that path. Asking the dictionary again for the value is needed because sorted provides a ...

We’ll assign a list to a variable, and then iterate through the list: sharks=['hammerhead','great white','dogfish','frilled','bullhead','requiem']forsharkinsharks:print(shark) Copy In this case, we are printing out each item in the list. Though we used the variableshark, we could ...

循环神经网络,然后hui用Theano(一个可以在GPU上进行运算的库)对实现进行优化。我会跳过一些对理解循环神经网络不是很重要的代码片段,但完整的代码可以在这里找到。 语言模型 这里的目标是用RNN构建一个语言模型,下面会解释一下什么是语言模型。假设有一个包含 ...
