Question

Добрый день! Помогите, пожалуйста, найти ошибку в программе♡Python Текстовый файл содержит только заглавные буквы латинского алфавита (ABC…Z). Определите максимальное количество идущих подряд символов, среди которых не более одной буквы D.f=open('C:/Users/7777/Downloads/24 (3).txt') s=f.readline() k=0maxK=0p=''for c in s: p+=c if p.count('D')<=1: k+=1 maxK=max(maxK,k) else: k=0 p=''print(maxK)Буду очень признательна за помощь)))♡​

Answer 1

f = open('C:/Users/7777/Downloads/24 (3).txt')

s = f.readline()

k = 0

maxK = 0

p = ''

for c in s:

   p += c

   if p.count('D') <= 1:

       k += 1

       maxK = max(maxK, k)

   else:

       p = p[:-1].split('D')[-1] + 'D'

       k = len(p)

print(maxK)

А это более сокращённый вариант:

k = 0

maxK = 0

temp = ''

for item in open('C:/Users/7777/Downloads/24 (3).txt').readline():

   temp += item

   if temp.count('D') <= 1:

       k += 1

       maxK = max(maxK, k)

   else:

       temp = temp[:-1].split('D')[-1] + 'D'

       k = len(temp)

print(maxK)

Вот, вроде бы так

Answer 2

Error in the Python Program

The provided Python program aims to determine the maximum number of consecutive characters in a text file where no more than one character is the letter 'D'. However, there is an error in the program that needs to be addressed. Let's analyze the code and identify the issue.

f = open('C:/Users/7777/Downloads/24+(3).txt')
s = f.readline()
k = 0
maxK = 0
p = ''
for c in s:
    p += c
    if p.count('D') <= 1:
        k += 1
        maxK = max(maxK, k)
    else:
        k = 0
        p = ''
print(maxK)

The error in the program lies in the line `k = 0maxK = 0p = ''`. There are missing spaces between the variable assignments. The correct line should be:

k = 0
maxK = 0
p = ''

After making this correction, the program should work as intended. It reads a text file, iterates through each character, and keeps track of the maximum consecutive characters where no more than one character is the letter 'D'. Finally, it prints the maximum count.

Please let me know if you have any further questions or if there's anything else I can assist you with!
