就我而言,这些行有问题,应该删除,而且你不能return
从 for 循环中删除,而只能从函数中删除:
return result('')
print(''.join(main(text)))
并重复这一行:
result.append(big_nums[i] + str( text_one))
在我重写你的代码之后:
def writeFile (filename, text):
with open(filename,'w') as file:
for line in text:
file.write(line)
def main():
result=[]
big_nums = ['no','One','Two','Three','Four','Five','Six','Seven','Eight','Nine','Ten']
text_one = (' green bottles \nHanging on the wall\n')
small_nums = [' no',' one',' two',' three',' four',' five',' six',' seven',' eight',' nine',' ten']
text_two = ('And if one green bottle \nShould accidentally fall\nThere\'ll be')
text_three = (' green bottles \nHanging on the wall\n \n')
new_string=''
text = new_string
for i in range(0,10):
result.append(big_nums[i] + str( text_one))
#result.append(big_nums[i] + str( text_one))
result.append(text_two + small_nums[i-1] + text_three)
#return result('')
#print(''.join(main(text)))
writeFile('greenBottle.txt',result)
main()
输出:
