[@naveenhagaragi8460]

At 6:40 & 14:35, i wrote below code to write data in different lines, when i print it. it was written in a single line. i opened the file from CWD and there also its written in a single line. >>> f2=open("xyz.txt","w") >>> lines=["Hello","Welcome to","Python Programming"] >>> f2.writelines(lines) >>> f2.close() >>> f2=open("xyz.txt","r") >>> f2.readlines() and output is : ['HelloWelcome toPython Programming'] Why it is not writing data in multiple lines as i have used writelines() function.???

[@naveenhagaragi8460]

got it, i need to include either at the beginning or at the end of each element of list. >>>lines=["Hello ","Welcome to ","Python Programming "]

[@guntadivya3505]

[@pannagabm2100]

Thank you sir.. ❤🙏

[@JayPatel-ou2ud]

nice sir

[@038anjalidevi2]

For suppose I don't want to close the file but I want cursor to be changed to a particular position. How is this made possible?

[@tarungarg2695]

what is the difference between .read() and .readlines() ? as you mention both will read complete file.

[@sumanpalisetty6096]

both are same until you pass an argument which is essentially the number of characters. if you pass read() or readlines() both are same if you have read(5), it will read only first 5 characters of a file. for readlines() there is no argument needed as it gives you complete file

[@naveenhagaragi8460]

If there are multiple lines in a file, ex: f1=open("file1.txt","w") lines=["Welcome to ","Python Programming "] f1.write(lines) read() will return each line data as it is in the file Ex: Welcome to python Programming but readlines() will return each line as an element of list. Ex: ["Welcome to ","Python Programming "]

[@anishatadkod1778]

You are so awesome sir ! Thank you 😊

[@rafimd407]

Using w+ we can open file in both write and read mode, then why to create new file pointer in read mode again?

Nice class tnx, but I thought by "open" we mean to open an existing document in the computer

[@sandraraynil]

It's like opening a Bank Account. You don't have any existing account in a bank, but you open "a new one".

Hi sir I have one doubt that If I am writing some data to file and want to read that data again How can I achieve this? As its write and read operation on same file and pointer shifting for each write operation.

[@singaiahs796]

f1=open("abc.txt" , "w") f1.write("hello how are you") f1.close( ) f1=open("abc.txt" , "r") print(f1.read( )) f1.close( )
