To open a file c:\test.txt for writing, we should use the statement:
- fobj = open("c:\test.txt", "w")
- fobj = open("c:\\test.txt", "w")
- fobj = open(file = "c:\test.txt", "w")
- fobj = open(file = "c:\\test.txt", "w")
Answer
fobj = open("c:\\test.txt", "w")
Reason — The syntax for 'open()' is: <file variable>/<file object or handle> = open(file_name, access_mode). Therefore, according to this syntax, fobj = open("c:\\test.txt", "w") is the correct statement to open a file for writing. The access mode "w" indicates that the file should be opened in write mode.
