This article is about how Python deletes the line number of each line in a file. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

1. What

This line number is really annoying. Try to write a py to remove it.

two。 Train of thought

Def second_of_str segmentation, take the element to the right of the delimiter and return a list

Def move passes in the file path, reads each line, stores the list, and calls the split second_of_str to save the new list.

The main function calls move

3. Code def second_of_str (str,splitsymbol): s = str.split (splitsymbol,1) # element # if len (s) = = 1: # return [] return s [1] def move (file_path, new_file_path): with open (file_path) Encoding='utf-8') as f: content = f.read (). Splitlines () # for line in content: # print (line) new_content = [] for line in content: new_line = second_of_str (line '.) # add a new list new_content.append (new_line) for line in new_content: print (line) F1 = open (new_file_path,encoding='utf-8') for each line after removal Mode ='w') for line in new_content: f1.writelines (line) f1.writelines (["\ n"]) f1.close () return new_contentif _ _ name__ = ='_ _ main__': f = move ('1.txt`)

Finished, the result ~
