deffilter_lines_by_keyword(filepath, keyword):withopen(filepath,'r', encoding='utf-8')asfile:
lines =file.readlines()
filtered_lines =[line for line in lines if keyword notin line]return filtered_lines
# 示例调用
filtered = filter_lines_by_keyword('example.txt','filter_keyword')for line in filtered:print(line.strip())
3.2. 过滤空行和注释行
有时候需要过滤掉空行和注释行(比如以#开头的行)。以下是实现这一功能的代码:
deffilter_empty_and_comment_lines(filepath):withopen(filepath,'r', encoding='utf-8')asfile:
lines =file.readlines()
filtered_lines =[line for line in lines if line.strip()andnot line.strip().startswith('#')]return filtered_lines
# 示例调用
filtered = filter_empty_and_comment_lines('example.txt')for line in filtered:print(line.strip())
from collections import Counter
defcount_word_frequency(txt_file):withopen(txt_file,'r', encoding='utf-8')asfile:
words =file.read().split()
word_freq = Counter(words)return word_freq
# 示例调用
word_freq = count_word_frequency('example.txt')for word, freq in word_freq.most_common():print(f'{word}: {freq}')
7.2. 生成词云图
对于可视化效果,可以生成词云图来显示词频分布:
from wordcloud import WordCloud
import matplotlib.pyplot as plt
defgenerate_word_cloud(txt_file):withopen(txt_file,'r', encoding='utf-8')asfile:
text =file.read()
wordcloud = WordCloud(width=800, height=400, background_color='white').generate(text)
plt.figure(figsize=(10,5))
plt.imshow(wordcloud, interpolation='bilinear')
plt.axis('off')
plt.show()# 示例调用
generate_word_cloud('example.txt')
8.自动生成txt报告
8.1. 从模板生成报告
可以使用txt模板生成报告,将动态数据填充到模板中。以下示例展示如何从模板生成报告:
defgenerate_report_from_template(template_file, output_file, data):withopen(template_file,'r', encoding='utf-8')as infile,open(output_file,'w', encoding='utf-8')as outfile:
content = infile.read()for key, value in data.items():
content = content.replace(f'{{{{ {key} }}}}',str(value))
outfile.write(content)# 示例调用
data ={'name':'Alice','date':'2024-08-17','summary':'This is a summary of the report.'}
generate_report_from_template('template.txt','report.txt', data)
8.2. 动态生成报告内容
有时候需要动态生成报告的内容,以下示例展示如何实现:
defgenerate_dynamic_report(output_file, sections):withopen(output_file,'w', encoding='utf-8')as outfile:for section in sections:
outfile.write(f'# {section["title"]}\n\n')
outfile.write(f'{section["content"]}\n\n')# 示例调用
sections =[{"title":"Introduction","content":"This is the introduction section of the report."},{"title":"Data Analysis","content":"This section contains the analysis of the data."}]
generate_dynamic_report('dynamic_report.txt', sections)
