- What is the value of the string variable
st when the
code below executes? Explain (to yourself or the class, you don't have
to write it down) your answer.
word = "creation"
st = ""
for i in range(0,len(word)):
if i % 2 == 0:
st = st + word[i]
print st # value here?
- The code below does the same thing as the code above, what do you
think the third parameter to
range does?
word = "creation"
st = ""
for i in range(0,len(word),2):
st = st + word[i]
print st # value here?
- The code below prints each of the numbers from 1 to 9 on a separate
line. How would you modify the code to print the numbers from 12
to 36, each on a separate line?
for num in range(1,10):
print num
- The sum of the numbers from 1 to 100, e.g., 1 + 2 + 3 + ... + 100
is 5050. Explain why the code below prints 4950 and explain how
to change one digit in the code -- that is change a '6' to a '5'
or a '0' to a '1', so that the code prints 5050.
total = 0
for num in range(1,100):
total = total + num
print total
