Assume that the variable $n$ refers to an integer. Write an expression that returns True if

and only if $n$ is divisible by either $2$ or $5.$

Suppose that the variable refers to a string. e$.$g$.,s=$ 'peach' or $s=$ 'watermelons $\text{'}.$ Write

an expression that revaluates to if and only if the $1^{st}$ character of $s$ is $\text{'}w\text{'}$

Suppose that the variable $s$ refers to a string. e$.$g$.,s=$ 'peach' or $s=$ 'watermelons $\text{'}.$ Write

an expression that revaluates to if and only if the last character of $s$ is $\text{'}s\text{'}$

Suppose that the variable refers to a string with odd length, e$.$g$.,($ or

$s=$ 'watermelons'. Write an expression that revaluates to True if and only if the middle

character of $s$ is $\text{'}a\text{'}$
