Python Data Persistence – Reading a File<\/h2>\n

Let us now read \u2018top-quotes.txt programmatically by opening it with r mode. When in R mode, the file object can call read (),<\/strong> readline ( )<\/strong> , and readlines ()<\/strong> methods.<\/p>\n

Out of these, the read ( )<\/strong> method can read a specified number of bytes from the file, the size defaults to file size. However, if the file is very big, the available memory restrictions may not allow the entire file to be read, so you may have to provide size parameters to read bytes at once.<\/p>\n

Example<\/strong><\/p>\n

>>> file=open ( ' top-quotes . txt' , ' r')\r\n>>> text=file . read ()\r\n>>> text\r\n\"'The best way to predict the future is to invent it.' - Alan Kay'\\nThere are only two kinds of programming languages: \r\nthose people always bitch about and those nobody uses.' - \r\nBjarne Stroustrup\\ n'The only way to learn a new programming language is by writing programs in it.' \r\n-Dennis Ritchie\\n'A computer would deserve to be called intelligent if it could deceive a human into believing that \r\nit was human.' - Alan Turing\\nprogramming languages have a devious influence.
