SGUSDA Python Basics

If we had a list "jointlist" that contained various integers, printing jointlist[0] would print:

• The first value

• The last value

• The average value in jointlist

• Nothing (null print)

The keyword "break":

• Terminates a loop

• Pauses a loop briefly

• Sub-divides a memory space

• Shatters reality

The built-in len() function returns:

• The number of elements in a collection

• The metric distance of a collection

• The L2 distance of a collection

• Measurements for a prismatic LENs

In Python, ranges and slices stop one short of the specified value. This annoying condition is due to:

• Python being a zero-indexed language

• Inaccuracy in the binary-to-decimal conversion

• Perl hackers

• Lisp hackers

Aside from tuples, the other immutable collection in Python is the:

• List

• Set

• Array

• String

If I wanted to reverse a string, I could slice it with:

• [::-1]

• [:::]

• [:backward]

• [.reverse()]

Tuples are immutable and:

• Ordered

• Disordered

• Unique

• Powerful

Assuming some file "input.txt", which parameter do we pass to the open() function to select READ mode?

• "r"

• "u"

• "w"

• "a"

While loops are for iterating so long as some condition holds true, and for loops are for:

• Iterating over a known range or collection

• Iterating without plan

• Iterating without cost

• Iterating over an unknown range or collection

The "not" operator is a boolean negator, flipping True to False and False to True if prepended (placed before) to them.

• True

• False
