Working on this problem for a python course and can't for the life of me figure out why this doesn't work. I'd rather it give me an error than print 0!
Problem gives me the variable x
with the string shown and need to print the index of the first time y
is used.
x = 'Poisson geometry plays an important role in noncommutative geometry.'
y = 'u'
i = 0
while i == 0:
for o in x:
if o == y:
print(y, "is first seen in index = ", y.index(o))
i += 1
Code shown returns:
u is first seen in index = 0
Did you want index in x
? In that case, use x.index(o)
where searches for o
in x
.
x = 'Poisson geometry plays an important role in noncommutative geometry.'
y = 'u'
i = 0
while i == 0:
for o in x:
if o == y:
print(y, "is first seen in index = ", x.index(o))
i += 1
However, the correct way to write it is without the loop:
x = 'Poisson geometry plays an important role in noncommutative geometry.'
y = 'u'
print(y, "is first seen in index = ", x.index(y))
output:
u is first seen in index = 51
You're essentially having it look for 'u'.index('u')
y.index(o)
should be x.index(o)
for this example.
Do you need to iterate? If you keep your first 2 lines then use x.index(y)
you will get the same result without using a while
, for
or if
.
x = 'Poisson geometry plays an important role in noncommutative geometry.'
y = 'u'
print(y, "is first seen in index = ", x.index(y))
