我有一段代码，其中有一个数组，该数组在字典的键数组之间循环。它获取每个键，将其应用于字典，然后获取返回值，并将其用于分隔我的unicode表。示例：
sizeDict = {
"Name": 16,
"Mobile": 11,
"Pizza": 7,
"Drink": 7,
"Dessert": 7,
"Total": 7
}
header = ['name', 'mobile', 'pizza', 'drink', 'dessert', 'total']
def printRow(firstChar, endChar, space, specialChar, spaceArray, spaceDict):
output = firstChar
for i in range(0, len(spaceArray)):
if(i == len(spaceArray) - 1):
specialChar = endChar
output = output + space * spaceDict[spaceArray[i].title()] + specialChar
return output
print(printRow("┏", "┓", "━", "┳", header, sizeDict))
#Returns ┏━━━━━━━━━━━━━━━━┳━━━━━━━━━━━┳━━━━━━━┳━━━━━━━┳━━━━━━━┳━━━━━━━┓
出于某种原因，问题在于即使两个字符串完全相同，它也无法将数组中的某些值识别为字典中的实际键。这是发生错误的特定数组，字典和错误消息。

答案 0 :(得分：2)
事实上
"% of Total".title()返回% Of Total。
这说明了您的错误
