Python學習日誌--文件讀寫

在編程過程中經常需要文件讀寫，Python的文件讀寫要比Java簡單的多。

打開文件的集中方式：

# 1.只讀
open("path/filename","r")

# 2.只寫
open("path/filename","w")

# 3.追加
open("path/filename","a")

# 讀取整個文件
file = open("path/filename","r")
file.read()

# 讀取一行文件
file = open("path/filename","r")
file.readline()

# 按行讀取文件返回一個迭代器
file = open("path/filename","r")
lines = file.readlines()

# 寫入文件
file = open("path/filename","w")
file.wirte("content")

# 追加的方式寫入文件
file = open("path/filename","a")
file.write("content")
