with open$(\text{'}$test$.$txt$\text{'},\text{'}$at$\text{'})$ as file:

for lithe in file:

print$($line$,$ end$=\text{'}\text{'})$

$($True$/$False$)$: In Part $1,$ By using open$(\text{'}$test$.$txt$\text{'},\text{'}$w$\text{'})$ and writing a string to the file, any existing content in test.txt will be erased before writing the new string.

$($True$/$False$)$: In Part $2,$ Opening the file in $\text{'}r+\text{'}$ mode will append the second quote to the en of the file without overwriting existing content.

$($True$/$False$)$: In Part $3,$ When the file is opened in $\text{'}a+\text{'}$ mode, the file pointer is initially positioned at the end of the file, and the for loop will not have any effect.

$($True$/$False$)$: By swapping the modes in Part $2$ and Part $3,$ from $\text{'}r+\text{'}$ to $\text{'}a+\text{'}$ in Part $2$ and usin $\text{'}r+\text{'}$ in Part $3$ for reading, both quotes will be printed.

$($True$/$False$)$: Part $3$ is a safe way to open the file since the with statement creates a block that automatically closes the file after the printing operation.
