Python 计数段落
Python Count paragraph
大家好,我的任务是统计行数和段落数。计算每一行显然很容易,但我坚持计算段落。如果一个段落没有字符,它将返回数字零,并且每个段落的增量都更高。例如输入文件是:Input and an Output should come out Output
所以我的代码是:
def insert_line_para_nums(infile, outfile):
f = open(infile, 'r')
out = open(outfile, 'w')
linecount = 0
for i in f:
paragraphcount = 0
if '\n' in i:
linecount += 1
if len(i) < 2: paragraphcount *= 0
elif len(i) > 2: paragraphcount = paragraphcount + 1
out.write('%-4d %4d %s' % (paragraphcount, linecount, i))
f.close()
out.close()
def insert_line_para_nums(infile, outfile):
f = open(infile, 'r')
out = open(outfile, 'w')
linecount = 0
paragraphcount = 0
empty = True
for i in f:
if '\n' in i:
linecount += 1
if len(i) < 2:
empty = True
elif len(i) > 2 and empty is True:
paragraphcount = paragraphcount + 1
empty = False
if empty is True:
paragraphnumber = 0
else:
paragraphnumber = paragraphcount
out.write('%-4d %4d %s' % (paragraphnumber, linecount, i))
f.close()
out.close()
这是一种方法,但不是最漂亮的方法。
import re
f = open('a.txt', 'r')
paragraph = 0
lines = f.readlines()
for idx, line in enumerate(lines):
if not line == '\n':
m = re.search(r'\w', line)
str = m.group(0)
try:
# if the line is a newline, and the previous line has a str in it, then
# count it as a paragraph.
if line == '\n' and str in lines[idx-1]:
paragraph +=1
except:
pass
if lines[-1] != '\n': # if the last line is not a new line, count a paragraph.
paragraph +=1
print paragraph
