python文件对象提供了两个“写”方法: write() 和 writelines()。 write()方法和read()、readline()方法对应,是将字符串写入到文件中。 writelines()方法和readlines()方法对应,也是针对列表的操作。它接收一个字符串列表作为参数,将他们写入到文件中,换行符不会自动的加入,因此,需要显式的加入换行符。 f1 = op...
In Python, temporary data that is locally used in a module will be stored in a variable. In large volumes of data, a file is used such as text and CSV files and there are methods in Python to read or write data in those files. After reading this tutorial, you’ll learn: – Readin...
fo = open(“C:/Documents/Python/test.txt”, “r+”) In the above example, we are opening the file named ‘test.txt’ present at the location ‘C:/Documents/Python/’ and we are opening the same file in a read-write mode which gives us more flexibility. ...
