缩进不对，改成我这样就行了。我试过了。

sum = 0
x = 0
while True:
    x = x + 1
    if x > 100:
        break
    if x%2==1:
        sum+=x
    continue
print sum

sum = 0
x = 0
while True:
x = x + 1
if x > 100:
    break
if x%2==0:

  continue

else

    sum+=x
print sum

sum = 0
x = 0
while True:
x = x + 1
if x > 100:
    break
if x%2==1:
    sum+=x
continue
print sum
