1. open the IDLE text editor >>> idle3 2. declare a *string* variable that holds *the path to the text file*, =test.txt= >>> strPath="/home/kaiming/Documents/Python/text/text.dat" 3. open the file using the =open()= function >>> f=open(strPath) 4. Read the contents of ...
We can use the file object as an iterator. The iterator will return each line one by one, which can be processed. This will not read the whole file into memory and it’s suitable to read large files in Python. Here is the code snippet to read large file in Python by treating it as...

如果sep为None,则C引擎无法自动检测分隔符,但Python解析引擎可以,这意味着将使用Python内置的嗅探工具css . sniffer自动检测分隔符。此外,长度超过1个字符且与'\s+'不同的分隔符将被解释为正则表达式,还将强制使用Python解析引擎。注意,正则表达式分隔符容易忽略引用的数据。正则表达式的例子:“\ r \ t”。
