Python tutorial- write data to file


Write data to file


To write text to a file, we use write() method. The close() method will force the system to write data to the file. If you don’t write the close() method, the data are not written to the file immediately.

>>> open('Python_source\\test.txt','w')
>>> f=open('Python_source\\test.txt','w')
>>> f.write('Hello World')
>>>f.close()
>>> 

To write data many lines of data to the file, you need to use writelines() method.
>>> f=open('Python_source\\test.txt','w')
>>> st='''While C, and C++ programs run fast, Python programs run slower.
But Python is easy to learn and save development time.'''
>>> f.writelines(st)
>>> f.close() >>>
