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())
Python逐行读取文件内容thefile= open("foo.txt") line = thefile.readline() while line: print line, line = thefile.readline() thefile.close()Windows下文件
Thereadline()method reads a single line from a file object and returns it as a string, including any trailing newline character. Generally, we use thewhileloop to iterate over the file content. The loop continues as long aslineis not an empty string (indicating the end of the file). Inte...

基础用法是withopen(’file.txt’,’r’,encoding=’utf-8’) as f: content = f.read()。encoding参数特别重要，遇到中文乱码时，可尝试’gbk’或’gb18030’编码。当文件较大时，推荐逐行读取：forline in f: process(line)。注意Windows系统换行符是̊，Linux是，可用universalnewlines模式自动转换。读取PDF...
cat test.txt|whileread line;doname2=$line done echo $name2 在第一种情况下输出: ENSMUSG00000000078.7 32.83699 29.78868 38.58607 30.348110000000002 第二种情况则无输出。 出现这种不同,是因为管道的机制,这个使用管道之后while read line是在子shell中进行的,所以退出之后$name2就没有值了。并且,cat 会一次...
