请仔细阅读右侧代码,结合相关知识,在 Begin-End 区域内进行代码补充,完成以下需求: 为Gender(行索引5)列中的值创建频率表; 循环遍历字典中的每个键值对。以上面显示的格式显示输出。

```python
import pandas as pd
data = {'Name': ['Tom', 'Jack', 'Steve', 'Ricky', 'Vin', 'John'],
'Age': [28, 34, 29, 42, 25, 33],
'Country': ['US', 'Canada', 'UK', 'US', 'US', 'UK'],
'Gender': ['M', 'M', 'M', 'M', 'M', 'F']}
df = pd.DataFrame(data)
# Begin
gender_freq = df['Gender'].value_counts() # 统计Gender列中各个值的频数
print(gender_freq)
for key, value in data.items(): # 遍历字典中的每个键值对
print(f'{key}:')
for i in range(len(value)): # 遍历每个键所对应的值
print(f' {i}: {value[i]}') # 输出键所对应的值
# End
```
输出结果:
```
