我想从一个文件中复制文本并将文本写入另一个fi

Question

fob = open("LISA designshpe.txt", "r+")

foc = open ("n.txt","w+")
s = fob.readlines()

fob.close()

for a in s :

    line =foc.write( a )

foc.close()

Answer 1

只需使用writelines()：

foc.writelines(s)

Answer 2

应与Python 2.7及更高版本配合使用：

with open("infilename") as infile, open("outfilename", 'w') as outfile:
  # outfile.write(infile.read()) # read entire file at once
  outfile.writelines(line for line in infile) # read file line by line

或者只是复制文件：

^{pr2}$
