Python:for-key-in-gascoount:name错误：name'；煤气量'；没有定义

导入字符串
def getFile（）：
filename=input（'filename:'）#文件名应为.csv
文件=打开（文件名“r”）
firstline=True
Line=file.readline（）
如果行==无或行==''：
一无所获
if firstline:#我不想读取字段名
Line=file.readline（）#还有更多内容需要阅读
firstline=False，所以我跳过了。代码假定
返回文件
#计算字段中的（T）个数[正确]
def calcT（正确）：
全局计数
发现=错误
对于ch in correct:#依次查看每个字符
如果输入“tT”：
找到=真
如果发现：
t计数+=1
#字段中最不常见的字符串出现多少次[气体]
def气体计数（气体）：
全球煤气量
如果气体中的气体计数：
气体计数[气体]+=1
其他：
气体计数[气体]=1
最小值=100000
对于键入气体计数：
如果气体计数[键]<最小值：
最小=气体计数[键]
答案=[]
对于键入气体计数：
如果gasCount[键]==最小值：
答案。追加（键）
#查找字段[quant]中的值之和小于（408）
定义和数量（数量）：
全球qsum
如果数量<408：
qsum+=quant
代码=“0”
#“代码”字段中有多少值与格式9999（x9+）9不匹配？
def检查字符串（astring）：
如果len（代码）！=10:
返回错误
如果未在string.digits中搜索[0]：
返回错误
如果未在string.digits中搜索[1]：
返回错误
如果未在string.digits中搜索[2]：
返回错误
如果未在string.digits中搜索[3]：
返回错误
如果不使用astring[4]=='（'：
返回错误
如果不是string.ascii_小写形式的[5]：
返回错误
如果未将[6]括在string.digits中：
返回错误
如果不使用astring[7]=='+'：
返回错误
如果不使用astring[8]=='）'：
返回错误
如果未在string.digits中搜索[9]：
返回错误
返回真值
如果选中字符串（代码）：
全球帐户
帐户+=1
#（30）和（107）范围内[age]字段中数字的平均值是多少
def平均年龄（年龄）：
全球舞台
全球年龄统计
如果年龄>=30，年龄=2.482，并且长得很好，您（似乎）永远不会初始化气体计数。但如果这是第58行，您没有向我们显示完整的代码，所以很难说。即使您使用了
global
，您也必须在代码中的某个地方有一行类似于
gascoount={}
，才能将其初始化为空字典。初始化它是什么意思？对不起，我是新来的！我会用完整的代码编辑主帖子OK我编辑了主帖子下面的两个循环
minimate=
和
answers=
应该是它们上面定义的函数的一部分吗？错误真的出现在第63行上了吗？还是你从那以后更改了内容？
