What is the expected output of the following code if the file named non_zero_length_existing_text_file is a non-zero length file located inside the working directory?
What is the expected output of the following code if the file named non_zero_length_existing_text_file is a non-zero length file located inside the working directory?
The provided code attempts to open a file in read mode, read a single character from it, print the length of that character, and then close the file. Since the file is a non-zero length file located inside the working directory, the file opening operation ('open' statement) will succeed without raising an IOError. 'f.read(1)' will read one character from the file, which will have a length of 1. Therefore, the expected output of the code is 1.
Correct answer is "D" In case would not be found in directory, IOError exception would be caught, so it would print -1 and answer would be "A"
Correct answer is A As it could not find such a file or directory, an IOError exception could be caught and print -1
try: f = open('non_zero_length_existing_text_file', 'rt') d = f.read(1) print(len(d)) f.close() except IOError: print(-1)
Correct answer is D ie 1, f.read(1) will read one char from file so len of d will be 1
IOError exception would be caught, so it would print -1 and answer would be "A"
why IOError, it said that file would be present inside working directory
Correct answer D. If the file named 'non_zero_length_existing_text_file' is a non-zero length file located inside the working directory, the expected output of the provided code would be the length of the first character read from the file. However, the provided code only reads one character from the file and prints the length of that character. Therefore, the expected output would be 1 regardless of the content of the file. This is because len(d) will always return 1, as d contains a single character read from the file. If the file contains more than one character, only the first character will be read due to f.read(1), but the length of that character (which is always 1) will be printed. The remaining characters in the file will not be processed or printed in this code snippet.
Correct answer is "D", the file is in the working directory, so no need any path and there is no error.
Correct answer is C, it throws FileNotFoundError: [Errno 2] No such file or directory:
The file could not be found in your directory, but the instruction says that the file is located inside the working directory. The answer is D.1
