打印文件的前n行
题目要求：当用户输入文件名和行数（N）后，将该文件的前N行内容打印到屏幕上。def print_lines(file,n):
f1 = open(file,'r')
for i in range(int(n)):
print(f1.readline,end = ' ')
f1.close
file = input('which file do you want to print:')
n = input('how many rows do you want to print:')
print_lines(file,n)
以上程序，我的运行结果如下，请大佬问题出在哪？该如何改进？
<built-in method readline of _io.TextIOWrapper object at 0x000001A162DA81E0> <built-in method readline of _io.TextIOWrapper object at 0x000001A162DA81E0> <built-in method readline of _io.TextIOWrapper object at 0x000001A162DA81E0> f1.readline 忘记了加括号
close 忘了加括号
def print_lines(file,n):
f1 = open(file,'r')
for i in range(int(n)):
print(f1.readline(),end = '')
f1.close()
file = input('which file do you want to print:')
n = input('how many rows do you want to print:')
print_lines(file,n)
