Question

为什么下面的代码没有正确输出对应的字母？

输出number to letter is['\x03', '\x03']

final_numbers = [3, 3]
final_letters = []

for i in range(len(final_numbers)):
    print(i)
    number_to_letter=chr(final_numbers[i])
    final_letters.append(number_to_letter)

print ("number to letter is" + str(final_letters))

Answer 1

chr(3) returnsASCII码为3的字符（即'\x03'）
将数字转换为字符串 (int-str) 你必须做 str() 而不是 chr()

所以这样做：

final_numbers = [3, 3]
final_letters = []

for i in range(len(final_numbers)):
    print(i)
    number_to_letter=str(final_numbers[i])
    final_letters.append(number_to_letter)

print ("number to letter is" + str(final_letters))

或者如果你想这样做 chr()（尝试猜测结果是什么）

final_numbers = [115, 116, 97, 99, 107, 32, 111, 118, 101, 114, 102, 108, 111, 119]
final_letters = []

for i in range(len(final_numbers)):
    print(i)
    number_to_letter=chr(final_numbers[i])
    final_letters.append(number_to_letter)

print ("number to letter is" + str(final_letters))

为什么下面的代码不能正确输出对应的字母呢？

Why does the following code not output the corresponding letters correctly?

python

chr

ord
