Write the function is$\_$valid$\_$line$\_$data$($line$\_$data$\_$tuple$)$ that returns True if all the values in the data tuple are valid; otherwise it returns False.

Note:

Data values are valid if$,$ and only if$,$ they are not $-1$ or $\text{'}-1\text{'}.$ That is$,-1$ and $\text{'}-1\text{'}$ are considered to be invalid.

You must include all your code for part $2$ so far.

Your is$\_$valid$\_$line$\_$data function will typically be used to process the data generated by your data$\_$tuple$\_$from$\_$line function.

You must include your working data$\_$tuple$\_$from$\_$line function $-$ some tests will call it$.$

Your function must be general enough to handle any number of values in the data tuple.

That is$,$ we will test it with different length tuples.

For example:

Test Result

line $=$ 'SCE$-$INT$-500025441,2011-09-23,4\mathrm{.}48,35175,4094,90254,$Hermosa Beach,CA$\text{'}$

data$\_$tuple $=$ data$\_$tuple$\_$from$\_$line$($line$)$

result $=$ is$\_$valid$\_$line$\_$data$($data$\_$tuple$)$

print$($result$)$

True

line $=$ 'SCE$-$INT$-500671284,2015-03-26,7\mathrm{.}206122449,-1,0,92241,$DESERT HOT SPRINGS,CA$\text{'}$

data$\_$tuple $=$ data$\_$tuple$\_$from$\_$line$($line$)$

result $=$ is$\_$valid$\_$line$\_$data$($data$\_$tuple$)$

print$($result$)$

False

data $=(\text{'}$SCE$-$INT$-500671284\text{'},\text{'}2015-03-26\text{'},7\mathrm{.}206122449)$

result $=$ is$\_$valid$\_$line$\_$data$($data$)$

print$($result$)$

True
