我需要将多个 ASCII 文件的cellsize和xllcorner转换为. 我一直在尝试在 ASCII 文件的标题中覆盖它们,就像使用常规文本文件一样,如下所示:yllcornermkmfor rw_file in os.listdir(r"C:\Users\Marie\Test"): rw_file_path = os.path.join(r"C:\Users\Marie\Test", rw_file) with open(rw_file_path, 'r+') as f: # skip the first two lines of the header f.readline() f.readline() # convert the values of cellsize, xllcorner and yllcorner into km line3 = f.readline() header_x, xllcorner = line3.split() xllcorner_new = int(xllcorner) / 1000 f.seek(2) f.write(re.sub(header_x, xllcorner_new)) #third argument?? line4 = f.readline() header_y, yllcorner = line4.split() yllcorner_new = int(yllcorner) / 1000 f.seek(3) f.write(re.sub(header_y, yllcorner_new)) line5 = f.readline() header_size, cellsize = line5.split() cellsize_new = int(cellsize) / 1000 f.seek(4) f.write(re.sub(header_size, cellsize_new))但是当然函数 re.sub 需要三个参数。我不知道该怎么做。我仍然是初学者,所以我确信有一个简单的方法,但我找不到它。我可以以某种方式覆盖标题中的这些行,还是有其他方法?
