Python新手求教，还望详解！

想要实现实现的功能：

统计一个文本中的空格数和数字的个数。

具体如下：

文本：

4 8 15 16 23 42 520 I LOVE LOST.

得出结果：

number_counts = 7

space_counts = 13 ＃42和520之间有5个空格，4～42之间都是一个1个空格

更新部分：

根据 @banagoo 提高的答案，我的代码：(还是有问题？)

import os

os.chdir('/Users/apple/Desktop/Python/chapter')

file_name = "lost.txt"

space_counts = 0

number_counts = 0

with open(file_name, 'r') as f:

for line in f:

space_counts += len( line.split() )

number_list = [x for x in line.split() if x.isdigit()]

number_counts = len(number_list)

print "space_counts", space_counts

print "number_counts",number_counts

文本：

4 8 15 16 23 42 520 I LOVE LOST.

4 8 15 16 23 42 520 I LOVE YOU.

发现答案不对呀！求指教？

谢谢 @banagoo 的帮助，可运行的代码如下：

import os

os.chdir('/Users/apple/Desktop/Python/chapter')

file_name = "lost.txt"

space_counts = 0

number_counts = 0

number_list = []

with open(file_name, 'r') as f:

for line in f:

line = line.strip()

space_split_list = line.split(' ')

space_counts += len(space_split_list) - 1

for word in space_split_list:

if word.isdigit():

number_list.append(word)

number_counts = len(number_list)

print "space_counts", space_counts

print "number_counts", number_counts

可以尝试用正则表达式。input_str = '4 8 15 16 23 42 520 I LOVE LOST.'

space_split_list = input_str.split(' ')

space_counts = len(space_split_list) - 1

number_list = [x for x in space_split_list if x.isdigit()]

number_counts = len(number_list)import os

os.chdir('/Users/apple/Desktop/Python/chapter')

file_name = "lost.txt"

space_counts = 0

number_counts = 0

with open(file_name, 'r') as f:

for line in f:

line = line.strip() # 每行行首,行尾的空格会被忽略

space_split_list = line.split(' ')

space_counts += len(space_split_list) - 1

number_list = [x for x in space_split_list if x.isdigit()]

number_counts = len(number_list)

print "space_counts", space_counts

print "number_counts", number_counts
