在Python中,逐行读取文件是一个常见的操作。 你可以使用内置的open函数结合for循环来实现这一点。以下是一个简单的示例代码: python # 打开文件 with open('example.txt', 'r', encoding='utf-8') as file: # 逐行读取文件内容 for line in file: # 打印每一行 print(line.strip()) 在这个示例中: op...
try:withopen('data.txt', 'r')as file:line=file.readline()whileline:print(line.strip())line=file.readline()exceptFileNotFoundError:print("Error: File not found.")exceptIOError:print("Error: An I/O error occurred.") 2.2. Generator Function In Python, Generators are functions that generate...
