Python Development bisect

Now there are the following requirements:

"    to achieve such a function:    a class of students to make some assessment, the rules are: one    : [0-60)     --F-double    : [60-70)-    -D    Three: [ 70-80)  --C four    : [80-90   ]--B    five: [90-100]  --A ' "

The bisect in Python can achieve the above requirements

Operating effect:

#python bisect "To achieve such a function: to a class of students to make some assessment, the rules are: one: [0-60)--F: [60-70)--D Three: [70- ---C four: [80-90]--B five: [90-100]--a ######################################### you'll probably think of using: if ....    else ...
