C++调用python函数问题记录
问题1
# gm => excel
def export(gm, excel, select, unit, hide):
ret = read_gm(gm)
data = ret[0]
channels = ret[1]
msg = ret[2]
if msg == 'ok':
msg = write_excel(data, channels, excel, select, unit, hide)
if msg == 'ok':
os.system(f'"{excelfilepath}"')
return msg
msg = export(gmfilepath, excelfilepath, exportselect, resistanceunit, hidecolumn)
print(msg)
分析：PyImport_ImportModule会调用最底下的代码，而export调用的传入参数未被初始化，故报错。
问题2
# gm => excel
def export(gm, excel, select, unit, hide):
ret = read_gm(gm)
data = ret[0]
channels = ret[1]
msg = ret[2]
if msg == 'ok':
msg = write_excel(data, channels, excel, select, unit, hide)
if msg == 'ok':
os.system(f'"{excelfilepath}"')
return msg
分析：和问题1类似，excelfilepath未初始化。
