Python中读取txt文件的方法有多种。以下是常见的几种方法：
file = open("file.txt", "r")
content = file.read()
file.close()
with open("file.txt", "r") as file:
content = file.read()
with open("file.txt", "r") as file:
lines = file.readlines()
with open("file.txt", "r") as file:
for line in file:
# 处理每一行的内容
无论选择哪种方法，都需要确保文件存在且可读。另外，还需要注意文件路径的正确性和编码方式的匹配。
