本文針對python入門者提供了乙個檔案讀寫的例項,並且對程式進行了詳細的分析,保證剛接觸到python的入門者能理解。

main
(): infile = open("test1.txt","r") #test1 is a defined name; r
#represents the process mode of test1 is read;
outfile = open("test2.txt","w")# w represents the process mode
#of test2 is write;
countlines = countlens = 0
#define two varibles respectively
#represents the number of lines and char
for line in infile
countlines += 1
#the number of line adding
countlens += len(line) #the number of char adding
outfile.write(line) #copy test1 to test2 line by line
infile.close() #close the test1
outfile.close() #close the test2
main()
注意:在
infile = open(「test1.txt」,」r」)語句中,檔名test1要加檔案型別限制,如果僅僅是
infile = open(「test1」,」r」)就會報錯:
filenotfounderror: [errno 2] no such file or directory: 『test1』

python檔案讀寫(基礎)
1.開啟檔案 讀寫檔案是常見的io操作,python內建了讀寫檔案的函式,方便了檔案的io操作。檔案讀寫之前需要開啟檔案,確定檔案的讀寫模式。open函式用來開啟檔案,語法如下 open name,mode,buffering open函式使用乙個檔名作為唯一的強制引數,然後返回乙個檔案物件。模式 ...
