How to add new line to existing pandas dataframe? [duplicate]

Question

I have a pandas dataframe that has been defined as empty and then I would like to add some rows to it after doing some calculations.

I have tried to do the following:

test = pd.DataFrame(columns=['Name', 'Age', 'Gender'])

if #some statement:

test.append(['James', '95', 'M'])

If I try to print and then append to test shows

print(test)

test.append(['a', 'a', 'a', 'a', 'a', 'a'])

print(test)

>>>

Empty DataFrame
Columns: [Name, Age, Gender]
Index: []
Empty DataFrame
Columns: [Name, Age, Gender]
Index: []

So clearly the line is not being added to the dataframe.

I want the output to be

Name | Age | Gender
James | 95 | M

Answer 1

Use append with dictionary as:

test = test.append(dict(zip(test.columns,['James', '95', 'M'])), ignore_index=True)

print(test)
    Name Age Gender
0  James  95      M

Answer 2

Try to append it as dictionary:

>>> test = test.append({'Name': "James", "Age": 95, "Gender": "M"}, ignore_index=True)
>>> print(test)

Outputs:

    Name Age Gender
0  James  95      M
