在python中处理异常的最简单方法是使用“ try-except”块。
try:
fob = open("test.txt", "r")
fob.write("This is my test file for exception handling!!")
except IOError:
print "Error: can\'t find the file or read data"
else:
print "Write operation is performed successfully on the file"
fob.close()输出结果
Error: can't find the file or read data
