Python學習知識整理（2）-將文件以行分割讀取成數組形式

這一系列博客僅用於記錄自己在學習python過程中的一些知識點。

將文件以行分割讀取成數組形式

代碼如下：

#!/usr/bin/env python
# -*- coding:UTF-8 -*-
# Python Version 2.7.5

# 函數用途：將文件以行分割讀取成數組形式
# 參數：FILENAME: str。非空字符串。文件全路徑。例如：/var/log/a.txt
# 返回值：LINES_ARR: list。數組。將文件按行分割，保存在數組裏。

def ReadFileToArray(FILENAME):
    FILE_TMP = open(FILENAME, "r")
    LINES_ARR = []
    for LINE in FILE_TMP:
        LINES_ARR.append(LINE)
    FILE_TMP.close()
    return LINES_ARR

if __name__ == '__main__':
    FILEA = "/root/filea.txt"
    FILEA_ARR = ReadFileToArray(FILEA)
    print ("FILEA_ARR[0] is " + FILEA_ARR[0])
    print ("FILEA_ARR[1] is " + FILEA_ARR[1])
    print ("FILEA_ARR[2] is " + FILEA_ARR[2])

執行結果：

[root@LvZS-CentOS7 ~]# cat filea.txt 
This is the first line
This is the second line
This is the third line
[root@LvZS-CentOS7 ~]# 
[root@LvZS-CentOS7 ~]# 
[root@LvZS-CentOS7 ~]# python FileToArray.py 
FILEA_ARR[0] is This is the first line

FILEA_ARR[1] is This is the second line

FILEA_ARR[2] is This is the third line
