This is mostly an exercise in formatting. Have a fixed minimum field width for cach field (column).
The first column is string type, the second is integer with a sign for both positive and negative
numbers, the third column is floating point with a precision (number of digits after the decimal
point) of three, and the last column is general (g') with a precision (here the maximum number of
digits before and after the decimal point) of seven. (See the informal on the giG format type below.)
Use the split () string method to isolate the fields in an input line, and use int () and float ()
to convert string values to integers or floating-point numbers, respectively.
Format type g/G
The format type g has the form m. pg, where mis the minimum field width and p is the precision.
Here, unlike with £, the precision is the number of digits after and before the decimal point. If the
integral part cannot all be represented because the precision is too small, we get exponential
notation eg.
>>> "(0:.4g)".format (12345.67)
1.235e+04
If the precision is large enough so that all the integral part can be represented, we get floating-
point notation e.g.,
» "(0:.5g)".format (12345.67)
"12346
>> "(0:.6g)".format (12345.67)
"12345.7
As with the eE format type, when g/G results in exponential notation, the exponent is introduced
with an 'e' if g is used, and with an 'E' is G is used eg.
>>> "(0:.4G)". format (12345.67)
'1.235E+04
