Question

Hello everyone! I want a little help on this code.
What's the error?
....

def isWordGuessed(secretWord, lettersGuessed):
j=0
if len(lettersGuessed)==0:
return False
for i in range(len(secretWord)):
for k in range(len(lettersGuessed)):
if secretWord[i]==lettersGuessed[k]:
j+=1
else:
j=j

if j>=len(secretWord):
return True
else:
return False

Answer 1

Ac.. to what i got from your code, you must move the last if-else block out of for-loops as the condition in if-else block i.e. j>=len(...) is never going to be true and it'll return false in first step of for loop. Plus the j=j statement is also not needed in else block.

def isWordGuessed(secretWord, lettersGuessed):
j=0

if len(lettersGuessed)==0:
return False

for i in range(len(secretWord)):
for k in range(len(lettersGuessed)):
if secretWord[i]==lettersGuessed[k]:
j+=1

if j>=len(secretWord):
return True
else:
return False

print(isWordGuessed("Hello", "Hello"))

Answer 2

Ya. Exactly. Thank you.
Actually, I'm a C++ programmer, so i don't know perfect syntex of python.

Answer 3

And have you completed computeRoot function(Newton-Raphson method) in previous problem?

Answer 4

I'm also, but i'm not studying courses here (from MIT/OCW), im studting from Udacity.

Answer 5

Great! Can you help in one more problem which one I'm going to post?

Answer 6

This is the code, in which we have to compute a root using Newton-Rashson method....
def computeRoot(poly, x_0, epsilon):
i=0
if len(poly)==1:
root=0

elif len(poly)>1:
root=x_0
while evaluatePoly(poly,root)<abs(epsilon):
deriv_poly=computeDeriv(poly)
root=root-(evaluatePoly(poly,root)/evaluatePoly(deriv_poly,root))
i+=1

a=[root,i]

return a

Answer 7

hey! Are you there?

Answer 8

Wait

Answer 9

Wait is problem ?
