Joining values from a DataFrame row with comma being separator

My DataFrame row line = fd.iloc[0] is:

id                         31458598
total_matched             104671.25
market           Under 3.5 Goals FT
one                               0
two                               0
three                             0
four                              0
five                              0
Name: 0, dtype: object

I have join this values with comma, like this:

f"{line['id']},{line['total_matched']},{line['market']},{line['one']},{line['two']},{line['three']},{line['four']},{line['five']}\n"

But this method is archaic, so I tried to use join:

','.join(line) + '\n'

TypeError: sequence item 0: expected str instance, numpy.int64 found

line.join(',') + '\n'

AttributeError: 'Series' object has no attribute 'join'

What is the correct way to join these values with a comma?

>Solution :

You can use str.cat after ensuring you have strings:

line.astype(str).str.cat(sep=',')

output: '31458598,104671.25,Under 3.5 Goals FT,0,0,0,0,0,0'
