Return centered in a string of length width. Padding is done using the specified fillchar (default is a space). Changed in version 2.4: Support for the fillchar argument. str.count(sub[, start[, end]]) 返回sub子串的数量 Return the number of non-overlapping occurrences of substring sub in...

It might appear at first that the default separator for split is a single space ' ', but as per the docs If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no ...
