如何循环输出每一行

Question

此代码的 objective 是在列出天数时打印出一些列值。我得到的输出是第一天的列值。

days = final_merged_data['Day'].tolist()
for day in days:
    each_row = final_merged_data[final_merged_data['Day'] == days]

    message_partition = f"""
    [{day}]
    Solar_Power_Generated in MW = {str(each_row['Power_Solar'].tolist()[0])}
    Wind_Power_Generated in MW = {str(each_row['Power_Wind'].tolist()[0])}
    Total_Power_Generated in MW = {str(each_row['Total MW'].tolist()[0])}"""
    
print(message_partition)

我得到的输出与第 1 行的列值相同。

[12]
    Solar_Power_Generated in MW = 26.48
    Wind_Power_Generated in MW = 30.34
    Total_Power_Generated in MW = 56.82
[13]
    Solar_Power_Generated in MW = 26.48
    Wind_Power_Generated in MW = 30.34
    Total_Power_Generated in MW = 56.82

像这样的东西应该适用于列字典：

rows = final_merged_data.tolist()
for row in rows:
    message_partition = f"""
    [{row['Day']}]
    Solar_Power_Generated in MW = {str(row['Power_Solar'])}
    Wind_Power_Generated in MW = {str(row['Power_Wind'])}
    Total_Power_Generated in MW = {str(row['Total MW'])}"""
    
    print(message_partition)

或者，如果所有列都存储为字典中的列表，

rows = zip(final_merged_data['Day'].tolist(), final_merged_data['Power_Solar'].tolist(), final_merged_data['Power_Wind'].tolist(), final_merged_data['Total MW'].tolist())

for row in rows:
    message_partition = f"""
    [{row[0]}]
    Solar_Power_Generated in MW = {str(row[1])}
    Wind_Power_Generated in MW = {str(row[2])}
    Total_Power_Generated in MW = {str(row[3])}"""
    
    print(message_partition)
