用Python写一个程序,其要能实现在Problem_C_Data_Wordle.csv文件当中读出Word那一列所对应的单词,并统计每个单词中各个字母的出现次数并输出到其对应的行当中

我可以提供一个简单的Python程序:import csv
with open('Problem_C_Data_Wordle.csv', 'r') as csv_file:
csv_reader = csv.reader(csv_file)
next(csv_reader)
for line in csv_reader:
word = line[1]
word_counts = {}
for character in word:
if character not in word_counts:
word_counts[character] = 1
else:
word_counts[character] += 1
line.append(str(word_counts))
print(line)

可以使用Python的pandas库来实现这个程序。
首先,导入pandas库和读取csv文件:
```python
import pandas as pd
df = pd.read_csv('Problem_C_Data_Wordle.csv')
```
然后,通过访问DataFrame中的"Word"列来获取单词:
```python
words = df['Word']
```
接下来,可以使用一个循环遍历每个单词,并统计每个字母的出现次数:
```python
for word in words:
letter_count = {}
for letter in word:
if letter in letter_count:
letter_count[letter] += 1
else:
letter_count[letter] = 1
# 将统计结果输出到对应行
index = words[words == word].index[0]
df.loc[index, 'Letter_count'] = str(letter_count)
```
最后,将统计结果保存到新的csv文件:
```python
df.to_csv('Problem_C_Data_Wordle_with_count.csv', index=False)
```
完整的程序代码如下:
```python
import pandas as pd
df = pd.read_csv('Problem_C_Data_Wordle.csv')
words = df['Word']
for word in words:
letter_count = {}
for letter in word:
if letter in letter_count:
letter_count[letter] += 1
else:
letter_count[letter] = 1
index = words[words == word].index[0]
df.loc[index, 'Letter_count'] = str(letter_count)
df.to_csv('Problem_C_Data_Wordle_with_count.csv', index=False)
```
注意:该程序假设'Problem_C_Data_Wordle.csv'文件中的'Word'列名是"Word",并且使用"Problem_C_Data_Wordle_with_count.csv"文件保存结果。

请见以下Python程序:
```python
import csv
from collections import Counter
# 打开CSV文件
with open('Problem_C_Data_Wordle.csv', 'r', encoding='utf8') as file:
reader = csv.reader(file)
header = next(reader) # 读取表头
# 获取Word列的索引
word_index = header.index('Word')
# 创建一个空字典,用来保存字母出现次数
letter_counts = {}
# 遍历每一行数据
for row in reader:
# 获取当前行的Word值
word = row[word_index]
# 统计当前单词中各个字母的出现次数
counts = dict(Counter(word))
# 将字母出现次数保存到letter_counts字典中
letter_counts[word] = counts
# 将字母出现次数写入到CSV文件中
with open('Problem_C_Data_Wordle.csv', 'r', encoding='utf8') as file:
lines = file.readlines()
with open('Problem_C_Data_Wordle.csv', 'w', encoding='utf8') as file:
writer = csv.writer(file)
writer.writerow(header) # 写入表头
for line in lines[1:]: # 遍历除表头外的每一行
row = line.strip().split(',')
word = row[word_index]
# 获取当前单词的字母出现次数
counts = letter_counts[word]
# 将字母出现次数添加到当前行
for letter, count in counts.items():
row.append(count)
writer.writerow(row)
print("字母出现次数已成功写入文件!")
```
以上代码将读取 `Problem_C_Data_Wordle.csv` 文件的 "Word" 列所对应的单词,并统计每个单词中各个字母的出现次数。最后,将字母出现次数依次插入到原CSV文件的每一行,并输出到文件中。
