Output

Notes:

①exit (0) Interrupt Program

② determines whether the input is a number that can be used with the IsDigit () method of the string

>>> "123". IsDigit () true>>> "abc". ISDIGIT () False

Exercise 36

Notes:

①if sentence Training Rules

• Each of the IF statements must contain an else

• If an else is meaningless and should not be executed, then use the Die function to alert you

• Try to keep only one layer of IF. Although if statements can be nested, try not to nest if, use functions instead of

• Treat the IF statement block as a paragraph. Line spacing before, left blank line after paragraph

• A Boolean expression should be simple. If it is too complex, assign the operation to the variable beforehand and give the variable a good name

② Cycle Law

• Use While-loop only if the expected loop never stops, and in other cases, especially if the number of objects in the loop is fixed or limited, the For-loop loop is used

③debugging's Skills

• Use Print to print key key variables and check for errors

• Side write script, side run, side debugging
