Python 删除整个文本中的空格,并实现按行显示

#encoding = utf-8#

ifn = r"firstname.txt"
ofn = r"Output.txt"

infile = open(ifn,'rb')
outfile = open(ofn,'wb')

for eachline in infile.readlines():
  lines = eachline.split('　')
  for temp in lines
    print temp
    outfile.write(temp+'\n')

infile.close
outfile.close

#只剩下数字，空格和.
import os,sys,string
str = "12.mengegsihello."
result = filter(lambda ch:ch in '.0123456789 ',str)
print result

#过滤掉所有的数字，空格和.，可以根据需要设置任何符号
import os,sys,string
str = "12.mengegsihello."
result = filter(lambda ch:ch not in '.0123456789 ',str)
print result
