Python reads the file by row and removes the line break "\ n" (check your eyesight, compare documents differently) __python

File1=input ("Enter the filename you want to open:") + ". txt"
f1=open (File1, "R") for
line1 in F1.readlines ():
    Line1=line1.strip ( "\ n")
    print (line1)

Extensions: Compares the two files entered by the user and, if different, displays the position of the line number and the first different character at all different points.

def file_compare (file1,file2):
    with open (File1) as F1, open (File2) as F2:
        count=0 #统计行数
        differ=[] #统计不一样的数量 For

        line1 in F1:
            line1=line1.strip ("\ n")
            Line2=f2.readline ()
            line2=line2.strip ("\ n")
            count +=1
            if Line1!=line2:
                differ.append (count) return

        differ

file1=input ("Enter the first file name you want to compare:") + ". txt "
file2=input (" Enter the first file name you want to compare: ") +". txt "

differ=file_compare (file1,file2)

If Len (differ) ==0:
    print ("Two files in exactly the same")
else:
    print ("Two files have a total of"%d "Different:"%len (differ)) for every in
    differ:
        print (" Line%d not the same "%each)
