字符串也是可迭代对象，可以通过for-in循环逐个访问字符：# 字符串示例word = "Python"# for-in循环遍历字符串for char in word: print(char)输出：Python 字典遍历示例 对于字典，for-in循环默认遍历其键：# 字典示例ages = {'Alice': 25, 'Bob': 30, 'Charlie': 35}# for-in循环遍历字典的键for ...
for example, if we have a text that’s too long to display and we want to show just a portion of it. Or if we want to make an acronym by taking the first letter of each word in a phrase. We can do that through an operation calledstring indexing.This...

for para in doc.paragraphs: print(para.text) 1.4 优缺点 python-docx是一个强大且易用的库,使得在Python中处理Word文档变得高效且便捷,适合各种自动化办公任务和文档生成需求。 二、文档Document结构 通过官方文档的分析,直接给大家两个结构图,如下:
for循环用于遍历一个可迭代对象中的元素,并执行相应的操作。下面是一个示例代码: AI检测代码解析 words=["Hello","world","!"]forwordinwords:print(word) 1. 2. 3. 在上述代码中,我们使用for循环遍历了一个列表中的元素,并将每个元素打印出来。
[] for word in string_list: word1 = "" for charecter in word: letter_position = alphabet.index(charecter) letter_position_with_shift = letter_position + num if letter_position_with_shift > 25: letter_position_with_shift = 0 + ((letter_position - 25) - 1) word1 += charecter....
