Python：跳过错误消息并继续在python循环中？

Question

当data1不在file_i.hdf5中时：

KeyError: "unable to open object (Symbol table: Can't open object)"

Answer 1

使用try:和except(KeyError):来捕获异常，如此。

import h5py

for i in range(0,100):
    try:
         with h5py.File('file_%s.hdf5' % i) as f:
             my_data = f['data1'][:]
             print i
    except(KeyError):
        # more code goes here...
