如果你已经安装了 Python,可以跳过这一步。 3.2 编写函数 首先,我们需要编写一个函数,这个函数将返回一个 list 类型的结果。下面是一个简单的示例函数,用于将一个字符串列表中的所有元素转换为大写。 defconvert_to_uppercase(strings:list[str])->list[str]:result=[]forstringinstrings:result.append(string.up...
24 print(string.ascii_lowercase) #所有的小写字母 25 print(string.ascii_uppercase) #所有的大写字母 26 print(string.punctuation) #所有的特殊字符 27 print('欢迎登录'.center(50,'*')) #*加‘欢迎登录’总共50个字符,把‘欢迎登录’放中间 28 29 l=['zhang','liu','liang'] 30 res = ','.jo...
Python3相同长度的列表List对应元素相加 我们假设有三个长度相同的列表如下: uppercase_letters = ['A','B','C','D'] lowercase_letters= ['a','b','c','d'] digit= [1,2,3,4] 方法一:利用for循环,三个列表对应位置的元素直接相加。 added_list = []#列表相加的最后结果foriinrange(0, len(...

Python sort list by case By default, the strings with uppercase first letters are sorted before the other strings. We can sort strings regardless of their case as well. case_sorting.py #!/usr/bin/python text = 'Today is a beautiful day. Andy went fishing.' ...
在Python中,最基本的数据结构为序列(sequence)。序列中的每个元素都有编号,即其位置或索引,其中第一个元素的索引为0,第二个元素的索引为1,依此类推。在有些编程语言中,从1开始给序列中的元素编号,但从0开始指出相对于序列开头的偏移量。这显得更自然,同时可回绕到序列末尾,用负索引表示序列末尾元素的位置。
print(uppercase_cities) Output: ['NEW YORK', 'LOS ANGELES', 'CHICAGO', 'HOUSTON'] Method 4: Using enumerate() Theenumerate()function adds a counter to an iterable and returns it as an enumerate object. This can be particularly useful when you need both the index and the value of each...
Let’s see what happens when there exists uppercase letters. >>>L=["oranges","apples","Bananas"]>>>L.sort()>>>L['Bananas','apples','oranges'] That’s interesting.Bananasappears beforeapples The reason for that is because Python treats all uppercase letters to be lower than lowercase ...
We can easily adapt it to create a list of uppercase characters: alphabet = [] for x in range(ord('A'), ord('Z') + 1): alphabet.append(chr(x)) print(alphabet)The output is: ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N'...
