nothing to repeat at position 0 原因:pattern书写错误 ptn = re.compile('*[xls|xlsx]$') 解决:编译pattern时使用了‘*’,表示匹配任意个字符,但是*是一个闭包,需要一个作用对象,在前面加一个‘.’表示任意字符,才能表示语义“任意个任意字符”,即改成: ptn = re.compile('.*[xls|xlsx]$')...
Set to ``None`` to load the whole dataframe at once. reauth : bool, default False Force Google BigQuery to re-authenticate the user. This is useful if multiple accounts are used. if_exists : str, default 'fail' Behavior when the destination table exists. Value can be one of: ``'...
where a series of comparators switch two entries to be in either increasing or decreasing order. The algorithm, created by Ken Batcher in 1968, consists of two parts. First, the unsorted sequence is built into a bitonic sequence; then, the series is split multiple times into smaller sequence...
Functions are designed to return a single value, but it is sometimes necessary to return more than one value. The only way to do this is to package the multiple values in a single data structure, then return that. Thus, you’re still returning one thing, even though it potentially contain...
^ Bitwise XOR (exclusive OR) a ^ b • Each bit position in the result is the logical XOR of the bits in the corresponding position of the operands.• 1 if the bits in the operands are different, 0 if they’re equal. >> Bitwise right shift a >> n Each bit is shifted right ...
The conclusion is that you won’t have a clear idea of which error or exception you’re dealing with at a given moment.In practice, avoid doing something like this:Python try: do_something() except Exception: pass Apparently, your do_something() function can raise many types of ...
