What's wrong?
Source: coding_bat string2
problems:
Return the number of times that the string "code"appears anywhere in the given string, except we'll accept any letter for the 'd', so "cope" and "coe" count.
count_code('aaacodebbb') → 1
count_code('codexxcode') → 2
count_code('cozexxcope') → 2
created code:
def count_code(str):
count = 0
for i in range (len(str)-4):
if str [i:i+2] == 'co' and str [i+4] == 'e':
count+=1
return count
Invalid index offset value.Also, Python uses the name str as the class name, so it is better to use it as another name.
def count_code(text):
count = 0
for i in range (len(text)-3):
if text [i:i+2] == 'co' and text [i+3] == 'e':
count+=1
return count
if__name__=='__main__':
print(count_code('aaacodebbb'))
print(count_code('codexcode'))
print(count_code('cozexxcope'))
