Two days ago a friend said, want to implement a text file according to a fixed number of lines to split into multiple text files, but do not know how to achieve. If the amount of data is small manual segmentation is good, if the volume of data is very large, manual completion is too labor-intensive, also unrealistic. Then you need to use scripts to implement them. Since a friend wants to accomplish this task simply, it is better to record it and make

Python string replacement requires constant learning. Only continuous learning can be used better. Next, let's take a look at how to replace the Python string in actual use. This will help you in future use. Python string replacement Replace all matched substrings. Replace all substrings in the subject that match the regular expression regex with newstring R
