如何将打印函数 () 的结果存储到变量中以将其包含在 f 字符串中
How to store the result of a print function () into a variable to include it in a f string
我有以下数据框:
data={'Process_ID':['12345-98', '23547-75', '85763-99','44231-56','78456-00','53218-87'],
'Date': ['2021-06-30','2022-08-10','2021-06-15','2023-10-02','2024-04-03','2021-06-25'],
'Check': ['True','False','False','True','True','False']}
df=pd.DataFrame(data)
print(df)
输出如下:
Process_ID Date Check
0 12345-98 2021-06-30 True
1 23547-75 2022-08-10 False
2 85763-99 2021-06-15 False
3 44231-56 2023-10-02 True
4 78456-00 2024-04-03 True
5 53218-87 2021-06-25 False
我想 select 仅针对 check="True" 的行的进程 ID 和截止日期,所以我这样做了:
def printfunc():
df['Check']=pd.eval(df['Check'].astype(str).str.title())
out=df.loc[df['Check'],['Process_ID','Date']].T
for x in out:
print('Process ID:',out[x].values[0],'\nDue Date:',out[x].values[1],'\n')
content=printfunc()
content
输出:
Process ID: 12345-98
Due Date: 2021-06-30
Process ID: 44231-56
Due Date: 2023-10-02
Process ID: 78456-00
Due Date: 2024-04-03
现在,我想在 f 字符串中包含 'content variable',因为我会自动发送电子邮件来显示此信息。但是,当我尝试这样做时,它 returns 一个 'None' 值:
email_text=f"""
Dear,
The due dates for the processes are the following:
{content}
Thank you.
Best Regards,
"""
print(email_text)
输出:
Dear,
The due dates for the processes are the following:
None
Thank you.
Best Regards,
如何将此变量包含在 f 字符串中以便能够打印它?
print(df)
只是写入标准输出 str(df)
returns.
尝试:
def printfunc():
s=''
df['Check']=pd.eval(df['Check'].astype(str).str.title())
out=df.loc[df['Check'],['Process_ID','Date']].T
for x in out:
s+='Process ID:'+out[x].values[0]+'\nDue Date: '+out[x].values[1]+'\n\n'
return s
content=printfunc()
最后:
email_text=f"""
Dear,
The due dates for the processes are the following:
{content}
Thank you.
Best Regards,
"""
print(email_text)
解释:
这个函数只是打印它不返回任何东西的值,所以这就是你得到 'None'
的原因
所以我们创建了一个变量 s
并将空字符 ''
赋给它,然后在函数
的 for 循环中添加字符串并将其赋值回它
P.S: 抱歉解释不好...我不擅长解释事情 :(
