Answer #1

Please let me know in case of any issue.

Assuming answers= ['Y','N','N','Y','N','Y','Y','Y','N','N','N']

numYes = 0
numNo = 0

for k, val in enumerate(answers):
if( val == 'Y'):
numYes = numYes + 1
elif(val == 'N'):
numNo = numNo + 1

print "Number of 'Y': ", numYes
print "Number of 'N': ", numNo

percentYest = float(numYes)/len(answers)

print "Percentage of 'Y': ",percentYest

answers.sort()

for k, val in enumerate(answers):
if(val == 'Y'):
print "First index of 'Y': ", k
break
