PYTHON读取文件，再打印出来，多了一个换行

[bearnedzq]

我用的是python3.0，IDLE

f = open('data.txt', 'r')
for line in f.readlines():
    print(line)
f.close()

data.txt:

在IDLE上打印出来变成了下面这样，每打印一行，后面多了一个空行。
我尝试着将 data.txt的换行符换成了window格式，unix格式，mac格式，效果都一样。

正常吧，每行的\n并没有去掉，print默认又换行...

[feilniu]

把print(line)改成：
print(line,end='')
或
sys.stdout.write(line)

[bearnedzq]

明白了。
