针对你遇到的问题 with open(path, "rb") as f: filenotfounderror: [errno 2] no such file or dir,这通常意味着 Python 在尝试打开一个文件时未能找到指定的路径。以下是根据你的提示,详细分析可能的原因及解决方案: 确认path变量指向的文件路径是否正确: 确保path 变量中存储的路径是正确的。可以通过打印...
同样,在处理二进制文件时,我们需要使用二进制模式打开文件。 importinspect# 获取文本文件的路径file_path=inspect.getfile(open('text_file.txt','r'))print(file_path)# 获取二进制文件的路径file_path=inspect.getfile(open('binary_file.bin','rb'))print(file_path) 1. 2. 3. 4. 5. 6. 7. 8. ...
def copy_file(source_file_path, target_file_path): # 源路径和目标路径作为形参 with open(source_file_path, 'rb') as source_file: # 二进制读模式打开源文件,别名为 source_file with open(target_file_path, 'wb') as target_file: # 二进制写模式打开目标文件地址,别名为target_file target_file...
withopen('E:\python\python\test.txt','w')as f: f.write('Hello, python!') 要写入特定编码的文本文件,请给open()函数传入encoding参数,将字符串自动转换成指定编码 字符编码 要读取非UTF-8编码的文本文件,需要给open()函数传入encoding参数,例如,读取GBK编码的文件: >>> f =open('E:\python\python\...
代码语言:javascript 代码运行次数:0 运行 AI代码解释 with open('/path/to/file', 'r') as f: print(f.read()) 这和前面的try ... finally是一样的,但是代码更佳简洁,并且不必调用f.close()方法。 调用read()会一次性读取文件的全部内容,如果文件有20G,内存就爆了,所以,要保险起见,可以反复调用read...
with open(r'%s' % source_file_path, 'rb') as f: with open(r'%s' % target_file_path, 'wb') as f1: # 以r模式打开源文件,以w模式打开目标文件 for line in f: f1.write(line) 9、小练习:实现动态查看最新一条日志的效果 import time # tail -f a.txt with open('file.txt', mode=...
try:f=open('/path/to/file','r')print(f.read())finally:iff:f.close() 2.推荐方式:读取文件—–With Open 1).读取方式 每次如果都按照如上最终方案去写的话,实在太繁琐。Python引入了with语句来自动帮我们调用close()方法重点:!!!with 的作用就是自动调用close()方法 !!!
