python小汇总
输出更完善的异常信息
import sys
def PrintException(msg=''):
exc_type, exc_obj, tb = sys.exc_info()
f = tb.tb_frame
lineno = tb.tb_lineno
filename = f.f_code.co_filename
linecache.checkcache(filename)
line = linecache.getline(filename, lineno, f.f_globals)
print('EXCEPTION IN ({}, LINE {} "{}"): {}, {}'.format(filename, lineno, line.strip(), exc_obj, msg))
元组中单元素问题
test = []
test1 = []
test2 = []
for v in range(1,5):
test.append((v, ))
test1.append((v, v))
test2.append((v))
print(test, test1, test2)
单元素添加进元组的时候，需要加逗号。
