I am trying to change column value depends from the other column along its row then merge it to an existing excel file using the ADSL
column as my key.
I have a Data like this:
ADSL Status Result
2/134 WO No Server Answer
1/239 WO Faulty
2/94 FA Number
2/321 SP Voltage
This is an actual data, the Status
column has three possible value [WO, FA, SP] each value has equivalent Result
value.
example:
Status Equivalent Result Value
Battery Tone
Engage
WO No Dial Tone
No Server Answer
No Voltage
Number
SP Voltage
FA Faulty
Vacant
now in reality the Status
column is not getting the right value based on its equivalent Result
value. (see data above)
What I'm trying to do is to correct the status
value based on its equivalent value from Result
column
what is the easiest or efficient way to do this in python? I am not looking on a particular library tho. any help would be appreciated a lot. Cheers!
I believe need map
by Series
:
df2['Status'] = df2['Status'].map(df1.set_index('Result')['Status'])
If some values are not match is possible replace by original non NaN
s values:
df2['Status'] = df2['Status'].map(df1.set_index('Result')['Status']).fillna(df2['Status'])
