直接上代码：
l=["A","B","C","D"] f=open("k1.txt","w") f.writelines(l) f.close() # 输出样式：ABCD l=["A","B","C","D",1,2,3] f=open("k2.txt","w") f.write(str(l)) f.close() # 输出样式：['A', 'B', 'C', 'D', 1, 2, 3] l=["A","B","C","D"] str = '\n' f=open("k3.txt","w") f.write(str.join(l)) f.close() ''' 输出样式： A B C D '''
