It does not read more than one line. f=open("myfile.txt","r"); f.readlines() #Returns a list object. Note: The default mode to read data is text mode.

It returns a Boolean depending on how much whitespace was read. Hope this helped! To get all the data from a file, you can use the read() method of the file object, after opening the file for reading. In this case, the file object is changed and it will not be possible to retrieve the data from it again. You are opening the file as "w" , which stands for writable. Using "w" you won't be able to read the file. Use the following instead: 5 Apr 2018 "I:\Python\Python36-32\SamsPrograms\MovieListCSV.py", line 20, in readMovies for row in reader: io.UnsupportedOperation: not readable  f1.read() Traceback (most recent call last): File "", line 1, in io.
