test_string_1 = "ds NOUN ds"
test_string_2 = "I'm going to VERB VERB to the store and pick up a NOUN or two."
print process_madlib(test_string_1)
print process_madlib(test_string_2)
始终不返回任何值,如果我手动对其进行测试并更改“ i”都很好

您的代码在循环中使用的变量存在一些问题,特别是您应该使用lenght + i
而不是lenght + 1
。另外,您在错误的位置增加了i
。
这是一个有效的版本:
def process_madlib(text):
proc = ""
lenght = len("NOUN")
i = 0
while text[i:lenght + i] != '':
if text[i:lenght + i] == "NOUN":
proc = text[i:-1] + word_transformer("NOUN") + text[i + lenght:]
return proc
i += 1
return text
test_string_1 = "NOUN ds"
test_string_2 = "I'm going to VERB to the store and pick up a NOUN or two."
print(process_madlib(test_string_1))
print(process_madlib(test_string_2))

您似乎拼错了“ lenght”。它应该是“长度”。
除此之外,我认为您要使用的是len(i)。 这是中间的代码。
while text[i:len(text)+1] !='':
i +=1
if text[i:len(text)+1] == "NOUN":
proc= text[i:-1] + word_transformer("NOUN") + text[i+len(text):]
return proc
