Python/PSSE错误: TypeError:需要一个整数

Question

在尝试将信息加载到PSSE中时，我在代码末尾收到一个错误。我的目标是一旦所有的数据都按照我想要的方式进行了组织，下一步就是使用这些组织好的数据并将其导入PSSE。之前的一切都可以工作，但是一旦我使用了PSSE API，就什么都不能工作了。我得到这个错误: psspy.bsys(1,0,0.0,0.0,0，[],1，bus,0，[],0，[])文件".\psspy.py"，行46020，in bsys TypeError:需要一个整数。

import os, sys

PSSE_LOCATION = r"C:\Program Files (x86)\PTI\PSSE33\PSSBIN"
sys.path.append(PSSE_LOCATION)

LOAD_GEN_DATAFILE = 'C:\Users\RoszkowskiM\Documents\CSV Files\ASTECOR_TLA.csv'

psspy.psseinit(10000)
psspy.case(STUDY_CASE)



data = list(csv.reader(open(LOAD_GEN_DATAFILE)))
mydict = {}
for row in data:
year,location,bus,change,isload = row[0:5]
# convert the types from string to Python numbers

change= float(change)
bus = int(bus)

 #If this is a year not seen before, add it to the dictionary
 if year not in mydict:
    mydict[year] = {}

 busses_in_year = mydict[year]
 if location not in busses_in_year:
     busses_in_year[location] = []

 #Add the bus to the list of busses that stop at this location
 busses_in_year[location].append((bus, change,isload))


 # assume CSV has columns as described in the doc string
 year = raw_input("Select Year of Study: ")

 location = raw_input(" Select the number associated to the TLA Pocket Location:")

 if year in mydict and location in mydict[year]:  
  busses_in_year = mydict[year]
  print("Here are all the busses at that location for that year: ")
  for bus in busses_in_year[location]:
    print(bus)


 else:
    print("Invalid Year or Location")


if isload.isdigit() and int(isload):    
    psspy.bsys(1,0,[0.0,0.0],0,[],1,[bus],0,[],0,[])
    psspy.scal_2(1,0,1,[0,0,0,0,0],[0.0,0.0,0.0,0.0,0.0,0.0,0.0])
    psspy.scal_2(0,1,2,[0,1,0,1,0],[change,0.0,0,-.0,0.0,-.0,0])

Answer 1

for bus in busses_in_year[location]:
    print(bus)

这打印的是什么？从前面的代码中，我认为bus实际上是一个tuple

busses_in_year[location].append((bus, change, isload))

当您使用[bus]调用bsys时，它将在遍历bus之后使用busses_in_year[location]的最后一个值。函数bsys需要一个整数，但是您给了它完整的tuple。

我不确定如何修复您的代码，因为只乘坐一年中的最后一辆公交车可能没有意义，所以您可能需要首先修复它。

但是，如果您想正确地解压tuple (bus, change, isload)，您可以执行以下操作：

for bus, change, isload in busses_in_year[location]:
    print(bus)
