Python程序将起始位置和结束位置之间的中间数字转换为相应的字母表形式

Question

从用户处获取字符串和两个整数，并将中间数字转换为起始位置和结束位置之间的相应字母形式

def convert_digits( input_string, start_position, end_position ) :
new_string = input_string[:start_position]
digit_mapping = {
'0': 'ZERO',
'1': 'ONE',
'2': 'TWO',
'3': 'THREE',
'4': 'FOUR',
'5': 'FIVE',    
'6': 'SIX',
'7': 'SEVEN',
'8': 'EIGHT',
'9': 'NINE'
}

for index in range(start_position, end_position):
if input_string[index].isdigit():
mapped = digit_mapping[input_string[index]]
new_string = mapped

new_string += input_string[end_position + 1:]
return new_string

def convert_digits(input_string, start_position, end_position):
len_str = len(input_string)
if end_position > len_str:
end_position = len_str
if start_position < 0:
start_position = 0
elif start_position >= end_position:
start_position = end_position - 1
input_string = input_string[start_position:end_position]
digit_mapping = {
'0': 'ZERO',
'1': 'ONE',
'2': 'TWO',
'3': 'THREE',
'4': 'FOUR',
'5': 'FIVE',
'6': 'SIX',
'7': 'SEVEN',
'8': 'EIGHT',
'9': 'NINE'
}
input_string = list(input_string)
for index, char in enumerate(input_string):
if char.isdigit():
input_string[index] = digit_mapping[char]
return "".join(input_string)

print(convert_digits("ajoegh12ioh12oih", 0, 14))
