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...
python list元素相加 python 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] 1. 2. 3. 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...

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...
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。
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.' ...
