编写程序比较两个文件的不同

#编写一个程序比较两个文件的不同

print('请输入第一个文件名：',end='')
file1=input()
print('请输入第二个文件名：',end='')
file2=input()
count_line=0
count_times = []

f1 = open('F:\'+file1)
f2 = open('F:\'+file2)

for f1_each_line in f1:
    count_line += 1
    f2_each_line = f2.readline()
    if f1_each_line != f2_each_line:
        count_times.append(count_line)

f1.close()
f2.close()

total_dif = len(count_times)

print('两个文件共有%d处不同'% total_dif)

for each_different in count_times:
    print('第%d行不同'% each_different)

以下是封装成函数：

#编写一个程序比较两个文件的不同
def compare(file1, file2):
    count_line=0
    count_times = []
    f1 = open('F:\'+file1)
    f2 = open('F:\'+file2)
    for f1_each_line in f1:
        count_line += 1
        f2_each_line = f2.readline()
        if f1_each_line != f2_each_line:
            count_times.append(count_line)
    f1.close()
    f2.close()

    if len(count_times) == 0:
        print('两个文件完全一样')
    else：
        print('两个文件共有%d处不同'% len(count_times))
        for each_different in count_times:
            print('第%d行不同'% each_different)
file1=input('请输入第一个文件名：')
file2=input('请输入第二个文件名：')
compare(file1, file2)
