File "<stdin>", line 1, in <module> IndexError: list index out of range 当索引超出了范围时,Python会报一个IndexError错误,所以,要确保索引不要越界,记得最后一个元素的索引是len(classmates) - 1。 如果要取最后一个元素,除了计算索引位置外,还可以用-1做索引,直接获取最后一个元素: >>> classmates...

IndexError: index out of range Out[2]: (640, 360) As you mentioned, it prints the error, but also returns the correct output. As I look back at the test runs, all the tests I mention pass using pillow 3.0. However, I was assuming there were errors because the two errors originally...
字符串是Python中最常用的数据类型,而且很多时候你会用到一些不属于标准ASCII字符集的字符,这时候代码就很可能抛出UnicodeDecodeError: ascii codec cant decode byte 0xc4 in position 10: ordinal not in range(128)异常。这种异常在Python中很容易遇到,尤其是在Python2.x中。

也可以用行索引当连接键,使用参数left_index=True, right_index=True. 但是这种情况下最好用JOIN df_2 = pd.DataFrame({'key':['a','b','b'], 'data1':range(3)}) df_1 = pd.DataFrame({'key':['a','b','c'],'data':range(3)}) ...
