Question

Here’s my code:

# Note: Return a string of 2 decimal places.
def Cel2Fah(temp): 
    fah = float((temp*9/5)+32)
    fah_two = (%.2f) % fah
    fah_string = str(fah_two)
    return fah_string

Here’s what I should get:

>>> Cel2Fah(28.0)
    '82.40'
>>> Cel2Fah(0.00)
    '32.00'

But I get an error:

Traceback (most recent call last):
File "Code", line 4
fah_two = (%.2f) % fah
^
SyntaxError: invalid syntax

I’m not sure what is going on…

This doesn’t seem to work either for some reason:

# Note: Return a string of 2 decimal places.
def Cel2Fah(temp): 
    fah = temp*9/5+32
    fah_cut = str(fah).split()
    while len(fah_cut) > 4:
        fah_cut.pop()
    fah_shorter = fah_cut
    return fah_shorter

Answer 1

sucmac:~ ajung$ cat x.py 
def toF(cel):
    return '%.2f' % (cel * 1.8 +32)

print toF(0)
print toF(50)
print toF(100)

sucmac:~ ajung$ python x.py 
32.00
122.00
212.00
