It's from a slicer and I want to use it in a 3D-Printer, but the part with Exxx.xxxxx needs to be removed.它来自切片机，我想在 3D 打印机中使用它，但需要删除带有Exxx.xxxxx的部分。 Is there a way in python to read the text file and remove just this part? python 中有没有办法读取文本文件并仅删除这部分？

You can use regex:您可以使用正则表达式：
import re
t = '''
G1 X113.901 Y66.179 E225.40813
G1 X114.212 Y66.611 E227.87255
G1 X114.396 Y67.11 E230.33708
G1 X114.452 Y67.78 E233.45031
G1 X114.057 Y71.888 E252.56566
'''
pattern = re.compile(r'E[0-9]+\.[0-9]+')
print(re.sub(pattern, "", t))
