USING PYTHON PROGRAMMING LANGUAGE

2.3. Do you think Python will print anything different if you pass a floating point number to celsius? What would Python print for this expression? Explain >>>celsius(60.0) 24. Do you think the celsius function can deal with negative numbers? What will Python do with this expression? >>celsius(-3) 2.5. One of the expressions in the body of the countertop function calculates the area of the missing triangular piece: triangle ((x / 2) ** 2) / 2 Are all the parentheses required in this expression? Explain what would happen if the statement was rewritten in one of the following forms triangle - (x/2) ** 2/ 2 triangle = x/2 ** 2 / 2

CELSIUS FUNCTION:

def convertF(fTemp):
c = (fTemp - 32) * (5 / 9)
print(fTemp, "Fahrenheit is equal to %.0f" % c, "Celsius.")

fTemp = float(input("Enter Fahrenheit temp to convert: "))

convertF(fTemp)

Answer 1

Python has built in type() that determines the data type of any variable or value defined in our program, so it won't make any difference if we pass any floating point value or negative integer.

Enter Fahrenheit temp to convert: 66.e 66.0 Fahrenheit is equal to 19 Celsius.

Enter Fahrenheit temp to convert 3 -3.0 Fahrenheit is equal to -19 Celsius.

The converted temperature will be rounded off since we have given formatting %0.f i.e '0 digits after decimal'

triangle=((x/2) ** 2) / 2

triangle=( x/2) ** 2 / 2

they both will give same output because the operator precedence is like ( ) -> ** -> /

triangle = x / 2 ** 2/2 , here precedence will be first given to ' ** ' so it will be like 'x / 4 / 2' , therefore it will give different answer
