Python脚本在空闲Shell中运行，Bash为.py而不是.ex

Question

我试图在字典中查找值，检查它们是否符合条件（高于数字限制），并删除key:value pair 从字典里。这在空闲Shell和Bash中可以正常工作，但是一旦我转换文件并尝试作为可执行文件运行，就会卡住并抛出一个错误代码，指出字符串不能转换为float。程序启动，但在其中一个字典上调用“限制器”时挂断

我尝试过pyinstaller并将.py改为.command（mac）（chmod+x file.command，尝试过使用int（）

#brings str1 and str2 into single dictionary
def dictionizer(str1, str2):
  str1 = str1.strip().split('\n')
  str2 = str2.split('\n')
  str2 = filter(None, str2)
  d = dict(zip(str1, str2))
  return d

##brings dicitionaries together
def merge(d1, d2):
  merged = d1.copy()
  merged.update(d2)
  return merged

#synthesizes list of strings into dictionaries
d_burgers = dictionizer(burgers, burgers_kcal)
d_breakfast = dictionizer(breakfast, breakfast_kcal)
d_chicken = dictionizer(chicken, chicken_kcal)
d_salad = dictionizer(salad, salad_kcal)
d_fries = dictionizer(fries, fries_kcal)

#creates finds all values above/below limit, removes qualifying       key:value pairs
def limiter(d):
  for k,v in list(d.items()):
    if float(v) >= b_limit + 100:
      del d[k]
    if float(v) <= b_limit - 50:
      del d[k]
  return d

#asks for a kcal limit, divides that limit arbitrarily, creates limits for all meals
print('What is your kcal limit for the day?')
limit = float(input())
b_limit = limit*0.30 
l_limit = limit*0.35
d_limit = limit*0.35

#sets the original dict to the limited dict
d_breakfast = limiter(d_breakfast)
d_burgers = limiter(d_burgers)
d_chicken = limiter(d_chicken)
d_salad = limiter(d_salad)

Traceback (most recent call last):
  File "/Users/********/Desktop/*****/setup.command", line 68, in     <module>
    d_breakfast = limiter(d_breakfast)
  File "/Users/*******/Desktop/*****/setup.command", line 54, in  limiter
    if float(v) >= b_limit + 100:
ValueError: could not convert string to float:

我想我找到了一些更好的解决方案，至少可以减少可能阻碍转换的因素。现在它很明确地不会在一个看起来应该的点上转换：

def dictionizer(str1, str2): 
    str1 = str1.strip().split('\n') 
    str2 = str2.replace('\n', ',').split(',') 
    str2 = list(filter(None, str2)) 
    str2 = [float(i) for i in str2] d = dict(zip(str1, str2)) 
    return d 

仍然得到： str2=[str2中i的浮点（i）] ValueError:无法将字符串转换为浮点值：

为什么它不能将str2中的所有内容都转换成浮点呢？尝试整数，获取： str2=[int（i）表示str2中的i] ValueError:基数为10的int（）的文本无效：“”

Answer 1

尝试在函数：limiter中打印v，就在if条件之前。转换为启用控制台的.exe文件。检查v值

错误说明值v是字符串，无法转换为标志

有些词典的值不一致
