python 课后作业
def file_compare(f1_name,f2_name):f1 = open(f1_name)
f2 = open(f2_name)
count = 0
differs = []
for each in f1:
each2 = f2.readline()
if each == each2:
count += 1
else:
differs.append(count)
f1.close()
f2.close()
return differs
f1_name = input('请输入第一个文件名:')
f2_name = input('请输入第二个文件名:')
differs = file_compare(f1_name,f2_name)
if len(differs) == 0:
print('没有不同')
else:
print('文件%s和文件%s共有%d个不同' % (f1_name,f2_name,len(differs))
for each in differs:
print('第%d行不同' % each)
个人感觉没有问题，为啥倒数第二行'for each in differs:'，每次运行都会把冒号标红，蹦出来个invalid syntax
因为你第 28 行少了个右括号：
def file_compare(f1_name, f2_name):
f1 = open(f1_name)
f2 = open(f2_name)
count = 0
differs = []
for each in f1:
each2 = f2.readline()
if each == each2:
count += 1
else:
differs.append(count)
f1.close()
f2.close()
return differs
f1_name = input('请输入第一个文件名:')
f2_name = input('请输入第二个文件名:')
differs = file_compare(f1_name, f2_name)
if len(differs) == 0:
print('没有不同')
else:
print('文件%s和文件%s共有%d个不同' % (f1_name, f2_name, len(differs)))
for each in differs:
print('第%d行不同' % each)
