String1.

C = 'A'
code = ord(C)
print(code)

Результатом выполнения этого кода будет число 65, так как символ "A" имеет код 65 в кодовой таблице ASCII.

String2.

N = 65
symbol = chr(N)
print(symbol)

Результатом выполнения этого кода будет символ "A".

String3.

C = 'A'
prev_code = ord(C) - 1
next_code = ord(C) + 1

prev_symbol = chr(prev_code)
next_symbol = chr(next_code)

print(prev_symbol, next_symbol)

Результатом выполнения этого кода будет символ "Z" (предшествующий символу "A") и символ "B" (следующий за символом "A").

String4.

N = 5

for i in range(N):
    code = ord('A') + i
    symbol = chr(code)
    print(symbol)

Результатом выполнения этого кода будет вывод следующих букв: A, B, C, D, E.
