像strip（）之类的方法，一般是自己写的时候查文档找到的么？我是自己写伪代码没问题，写实际代码的时候找这种方法比较费时间和精力

import pprint import string with open("./24-demo.txt", encoding='UTF-8') as f: file_data = f.readlines() f1 = set(file_data) #转为集合，删除多余的换行符 f1.remove('\n') #删除最后一个独立换行符 f2 = [] for a in f1: f2.append(a.strip()) #将每行的换行符删除后添加到新列表 f3 = str(f2) #将列表所有元素合并为一个字符串 for c in string.punctuation: f3 = f3.replace(c, "") #删除字符串中的标点符号 f4 = f3.split(' ') #转为列表，作为计数的基础 f5 = set(f4) #转为集合去重，作为计数的项 f6 = {} for s in f5: f6[s] = f4.count(s) del f6[''] print(f6)

with open("24-demo.txt") as f: file = f.readlines() new_file = str(file).split(" ") dic1 = {} for i in new_file: dic1[i] = new_file.count(i) print(dic1)

有一些伙伴 pip 安装 tinydb 之后导入还是出现模块未找到的错误，这是因为安装了多个python或者使用了虚拟环境导致的，运行的 pip 不是 jupyter 内核使用的python解释器的那个 pip 就会出现这种问题，这时候可以使用以下方法解决 在 jupyter notebook 执行下面两行命令： import sys !"{sys.executable}" -m pip uninstall tinydb

with open("./demo.txt") as f: lines = f.readlines() symbol = [",", ".", "!", "?", "(", ")", "\n", " "] counter = {} for s in symbol: lines = " ".join(lines).split(s) for k in lines: if k: if k in counter: counter[k] += 1 else: counter.setdefault(k, 1) print(counter)

with open('./24-demo.txt') as f: data = f.readlines() list_key = str(data).split(' ') list_values = [list_key.count(a) for a in list_key] dict(zip(list_key,list_values))

with open('./boston.csv') as f: file_data = f.readlines() print(file_data) from tinydb import TinyDB db = TinyDB('./db.josn') print(len(file_data)) friend_list = [] for i in range(len(file_data)): friend = {'name': file_data[i].split(',')[0], 'source': file_data[i].split(',')[1], 'number': file_data[i].split(',')[2].strip()} friend_list.append(friend) print(friend_list)

不能写个循环吗？

不知道有没啥适合书可以推荐的书给大家

# Reading the file and counting word occurrences with open("/Users/yangaoyu/Downloads/zero-basics-python/3/24-demo.txt", "r") as f: # Read the content and split it into words words = f.read().split() # Convert to lower case for uniformity and then count occurrences word_counts = {} for word in words: # Remove punctuations and make it case-insensitive cleaned_word = ''.join(e for e in word if e.isalnum()).capitalize() if cleaned_word: word_counts[cleaned_word] = word_counts.get(cleaned_word, 0) + 1 print(word_counts)
