Question

在python 里如何用replace删除文本里所有的空行

Answer 1

非要用replace吗，我都是用
x for x in L where L!=‘\n'
来去除空行的

Answer 2

# coding=utf-8
file = open("blank.txt","r")
file2 = open("noblank.txt","w")
while 1:
text = file.readline()
if( text == '' ):
print "结束"
break
elif( text == '\n'):
print "换行符"
else:
file2.write( text )
print text
file.close()
file2.close()
raw_input()

Answer 3

eg:

a="dhfhf kgkg gjg"
b=a.replace(" ","")
