Adding a dictionary to tupleIn this problem, we are given a tuple and a dictionary. We need to create a Python program that will add the dictionary as an element to the tuple.Input: ('programming', 'language', 'tutorial') {1 : 'python', 4 : 'JavaScript', 9: 'C++'} Output: ('...
猜测 There should be one-- and preferably only one --obvious way to do it. # 而是尽量找一种,最好是唯一一种明显的解决方案(如果不确定,就用穷举法) Although that way may not be obvious at first unless you're Dutch. # 虽然这并不容易,因为你不是 Python 之父(这里的Dutch是指Guido) Now is...
index = [1, 2, 3] languages = ['python', 'c', 'c++'] dictionary = dict(zip(index, languages)) print(dictionary) Run Code Output {1: 'python', 2: 'c', 3: 'c++'} We have two lists: index and languages. They are first zipped and then converted into a dictionary. The zip...
第1 步:创建一个要放置库的目录「Step 1: Create a directory in which you want to put your library」 我创建一个文件夹名为:Turingaiyc,这个名称其实也是我后面发布库的名称,注意不要太普遍因为会重复,重复就会导致发布库失败。 I created a folder called Turingaiyc, which is actually the name of th...
Write a Python program to convert a tuple to a dictionary. Visual Presentation: Sample Solution: Python Code: # Create a tuple containing nested tuples, where each inner tuple consists of two elements.tuplex=((2,"w"),(3,"r"))# Create a dictionary by using a generator expression to swap...
Write a Python program to multiply all the items in a dictionary. Sample Solution: Python Code: # Create a dictionary 'my_dict' with keys 'data1', 'data2', and 'data3', along with their respective values.my_dict={'data1':100,'data2':-54,'data3':247}# Initialize a variable 're...
try: display = pygame.display.set_mode((640,0)) except pygame.error: print("Not possible to create display") exit() 因此,最好明智地选择您的显示屏,以消除任何不必要的异常。但更有可能的是,如果您尝试加载不在硬盘上的图像,您可能会遇到pygame错误的异常。因此,处理异常是一个很好的做法,以确保游...
We’re going to set up a simple dictionary where we have our first key that’s associated with a value object. 我们有第二把钥匙,和另一个物体在一起。 We have our second key that goes with another object. 假设我们这里有第四个键,它和相应的值对象一起。 And let’s say we have key num...
