['Shining with joy', 19.1, 1.69, 150.0],
['Rolling with laughter', 25.6, 0.774, 0.0],
['Tears joy', 233.0, 7.31, 2270.0],
['Wink', 15.2, 2.36, 264.0],
['Happy', 22.7, 4.26, 565.0],

['Thoughtful', 6.81, 0.636, 0.0],

['Two hearts', 10.0, 5.69, 445.0],

['Hearts', 3.31, 1.82, 697.0],
['Class', 23.1, 3.75, 227.0],
['Shrug', 1.74, 0.11, 0.0],
[ 'Fire', 4.5, 2.49, 150.0],
['Recycle', 0.0333, 0.056, 932.0]
]
print('Emoji Name | Twitter/Instagram Ratio')
print('------------ ------------------------------')
name = 0
ratio = 0
for row in data:
# save to "Emoji Name" variable (column 0)
name = data[0]
# save to "Twitter/Instagram Ratio" variable
# (column 3 to column 2)
ratio += data[3][2]
# output the string to screen
print('{: <16} | {: >29.2f}'.format(name, ratio))
Traceback (most recent call last):
File "main.py", line 43, in
print('{: <16 } |{: >29.2f}'.format(name, ratio))
TypeError: unsupported format string passed to list.__format__

Answer 1

for a long time

Answer 2

for row in data:
# сохраните в переменную «Название эмодзи» (столбец 0)
name = data[0]

And in the ratio calculation

# сохраните в переменную «Соотношение Твиттер/Instagram»
# (столбец 3 к столбцу 2)
ratio += data[3][2]

it was necessary to divide the value of column 3 by the value of column 2, i.e. row[3]/row[2] .
And it is not clear why the increment of the ratio value is here, according to the condition of the problem, it is clear that a separate value is required for each row, without summation.

Answer 3

Answer 4

name = 0
ratio = 0
for row in data:
name = row[0]
ratio = row[3]/row[2]
print('{: <16} | {: >29.2f}'.format(name, ratio ))
