A web page without a bibliography, or sources, is an indicator of an unreliable site. Please select the best answer from the choices provideda. True
b. False

Answers

Answer:

True indeed

Explanation:

true/false: if the last line in a file is not terminated with a \n, the readline method will return the line without a \n.

Answers

True, if the last line in a file is not terminated with a \n, the readline method will return the line without a \n.

In Python, the `readline()` method reads a single line from a file and returns it as a string. When the last line in a file is not terminated with a `\n` character, the `readline()` method will not recognize it as the end of the line and will return the line without the `\n` character. This occurs because the `readline()` method only reads up to the next `\n` character, and if it does not find one, it assumes that the line has not ended and includes the last line in its entirety. To avoid this issue, it is recommended to ensure that all lines in a file are terminated with a `\n` character, especially when using methods such as `readline()` to read the contents of the file.
