how i can loops thourgh column in each row using python-CodePudding

Hey you guy I got a dataframe like this

empoyees = [('jack', 34, 'Sydney',800) ,
       ('Riti', 31, 'Delhi',800) ,
       ('Aadi', 16, 'New York',800) ,
       ('Mohit', 32,'Delhi',1500) ,
        ]
empDfObj = pd.DataFrame(empoyees, columns=['Name', 'Age', 'City',Salary], index=['a', 'b', 'c', 'd'])

how I can loop through columns in each row and get the result like this using pandas in python. Maybe add all it into a small list of each row

a Name jack Age 34 City Sydney Salary 800
b Name Riti Age 31 City Delhi Salary 800
c Name Aadi Age 16 City New York Salary 800
d Name Mohit Age 32 City Delhi Salary 1500

You could use DataFrame.to_dict with orient set to 'index'

The output of dict would be of the form:

{ idx₁ : {col₁:val₁, col₂:val₂ ... col_n:va_n},
  idx₂ : {col₁:val₁, col₂:val₂ ... col_n:val_n},
  ...
}

Loop through the dict and create a list of strings if would like to store them as a list.

[
    f'{idx} {" ".join([str(v) for t in vals.items() for v in t])}'
    for idx, vals in df.to_dict("index").items()
]

# output
# ['a Name jack Age 34 City Sydney Salary 800',
#  'b Name Riti Age 31 City Delhi Salary 800',
#  'c Name Aadi Age 16 City New York Salary 800',
#  'd Name Mohit Age 32 City Delhi Salary 1500']

If you only want to print them you don't need to build a list of strings. You could do:

for idx, vals in df.to_dict('index').items():
    print(idx, *[v for t in vals.items() for v in t], sep=" ")

#output
# a Name jack Age 34 City Sydney Salary 800
# b Name Riti Age 31 City Delhi Salary 800
# c Name Aadi Age 16 City New York Salary 800
# d Name Mohit Age 32 City Delhi Salary 1500

i kept it simple

s=''
for index, row in df.iterrows():

    if index in s:
        pass
    else:
        s =str(index)
    for key, value in row[:].items():
        s =" "  key " " str(value)
    print(s)
    s=''

output

a Name jack Age 34 City Sydney Salary 800
b Name Riti Age 31 City Delhi Salary 800
c Name Aadi Age 16 City New York Salary 800
d Name Mohit Age 32 City Delhi Salary 1500
