我看過(guò)多個(gè)問(wèn)題帖子，我想知道如何擺脫文件的最后一行，或者說(shuō)是空白行infile = open("milkin.txt","r").readlines() outfile = open("milkout.txt","w") number = infile[0] arrayLoc = infile[1].split( ) array = infile[2].split( ) dictionary = {} for i, z in zip(arrayLoc, array): dictionary[i] = z for key in sorted(dictionary): outfile.write(dictionary[key]) outfile.write("\n") outfile:5520059808917271805406513926920236226414212897763238342614900271368690在數(shù)字下方有一條多余的線，我想將其刪除

錯(cuò)誤在這里：
outfile.write("\n")
應(yīng)該這樣做：
newline = ''
for key in sorted(dictionary):
outfile.write(newline)
outfile.write(dictionary[key])
newline = '\n'
由于文件newline初始化為空字符串，因此文件開(kāi)頭不會(huì)有空行。

或者：
infile = open("milkin.txt","r").readlines()
outfile = open("milkout.txt","w")
number = infile[0]
arrayLoc = infile[1].split( )
array = infile[2].split( )
dictionary = {}
for i, z in zip(arrayLoc, array):
dictionary[i] = z
for key in sorted(dictionary):
outfile.write(dictionary[key])
outfile.write("\n")
outfile.writelines([dictionary[key] if list(sorted(dictionary))[-1]==key else dictionary[key]+'\n' for idx,key in enumerate(sorted(dictionary))])
