python 对text进行读写小例子非常简单

Description:After modifying the strings in one text,I rewrote them in another text. The following python code is effective.

Code:

# change pointnamesfileread = open("allpointnames.txt", 'r')name = []name1 = []for line in fileread:    name.append(line)if name[len(name)-1][len(name[len(name)-1])-1] != "\n":    name[len(name)-1] = name[len(name)-1]+"\n"print(name)fileread.close()print(len(name))for i in range(0, 100):    #print(name[i][0])    s = str(2) + name[i][1:len(name[i])-1] +".net" +"\n"    name1.append(s)print(name1)filew = open("0_99pointnamestrue.txt", 'w')for line1 in name1:    filew.writelines(line1)filew.close()print(len(name1))

 If you use this piece of code,you are supposed to pay attention to the enter key.
