將指定文件中的空格或換行刪除(可選是否創建一個新文件)

代碼使用python3寫成，沒有難懂的地方，是個小白代碼，日後會改進，這裏先記錄一下，主要用於16進制導出的文件，其中空格與換行較多，寫個腳本，比較省勁，懶懶懶~~~

	# global_variable()
	f = open(file_input)
	for line in f.readlines():
		line = str(line.replace(' ',''))
		result += line.strip()
	f.close()
	# see_details()

	flag = True
	while flag:

代碼重複率比較高，大佬勿噴，小白們可以借鑑一下
