python如何复制文件内容到另一文件

用readline
inputFile = open("inputFile.txt", "r")
print "Name of the input file: ", inputFile.name;
outputFile = open("outputFile.txt", "a");
print "Name of the output file: ", outputFile.name;
allLines = inputFile.readlines();
for eachLine in allLines:
    print "current line content: %s" % (eachLine);
     
    #append into output file
    outputFile.write(eachLine);
 
inputFile.close();
outputFile.close();
