Ma'am if I run the "write command in VScode " it is not working. What should I do? Pls help... when I run the write command the text in the txt file is not overwriting as you said.... the text remains the same. Pls help..... 🙏🏽🙏🏽

mam , while replacing the word java to python , and after that the file should be overwritten, but when i was writing the code the file is not being overwritten but the new file is being created , which should not happen right?how should i come over this error.
The r+ does not always add the data at the beginning. its totally depends where the cursor is like if we use the read command and then write so in this case after reading data the cursor will be in the end and if then we use the write command then the new data will be added to the end of file: For example in this case: f = open("test.txt" , "r+") content = f.read() f.write("john" ) f.close() : now in this case "john" will be added to the end of file. so remember the cursor is not always in the beginning in r+ mode its totally depends what you have done before that line of code. Happy coding😊

13:18 Understanding file reading modes

21:17 Differences between different modes
25:09 Different file modes in Python: Read Plus, Write Plus, Append Plus
27:19 Using the 'with' syntax in Python automatically closes the file
31:48 We can delete any file by using the remove function in the os module.
34:24 Replace Java with Python in a file using the replace method.
38:59 Write a function to find the line number of the word 'learning' in a file.

Mam! this line is very motivational for me that you mentioned in start that "All power is within you you can do anything and everything"
The r+ does not always add the data at the beginning. its totally depends where the cursor is like if we use the read command and then write so in this case after reading data the cursor will be in the end and if then we use the write command then the new data will be added to the end of file: For example in this case: f = open("test.txt" , "r+")
content = f.read()
f.write("john" )
f.close() : now in this case "john" will be added to the end of file. so remember the cursor is not always in the beginning in r+ mode its totally depends what you have done before that line of code. Happy coding😊
