Loop Through a TupleYou can loop through the tuple items by using a for loop.ExampleGet your own Python Server Iterate through the items and print the values: thistuple = ("apple", "banana", "cherry") for x in thistuple: print(x) Try it Yourself » ...
#for loop in tuple for i in my_tuple: print (i)While loop in tupleYou can also use a while loop to iterate through a tuple by manually managing the index.#while loop in tuple my_tuple = (10, 20, 30, 40) index = 0 while index < len(my_tuple): print(my_tuple[index]) index...

In this third and final example, we will use a for loop and the setdefault() method to convert the list of tuples into a dictionary:my_dict = {} for i,j in my_tuples: my_dict.setdefault(i,[]).append(j) print(my_dict) # {'Name': ['John'], 'Age': [25], 'Occupation':...
And I can ask Python to print the value of x and y. 这就是这里发生的事情。 So this is what’s happening here. 坐标是元组列表。 Coordinates is a list of tuples. 在FOR循环中,我要遍历那个容器,那个坐标序列,一次一个。 In my FOR loop I am going over that container, that sequence of ...
for row in df.itertuples(): for post in row[ : len(row[3])]: new_row = [row[1], post ] data.loc[len(data)] = new_row 似乎内部的for-loop迭代了来自itertuples的结果,这使得速度非常慢! 即使我将单个用户抓取的帖子的最大数量限制为100篇,即使在高性能远程服务器上运行,代码也不会在数...

zipis a built-in function that takes two or more sequences and “zips” them into a list of tuples where each tuple contains one element from each sequence. In Python 3, zip returns an iterator of tuples, but for most purposes, an iterator behaves like a list. ...
