HELP WITH PYTHON!

I have a very large .txt file that has been converted into a matrix consisting of two columns: phenotype and gene. How do I organize the matrix so that the row has the gene values and the column has the phenotype values?

Example of original matrix:

Phenotype	Gene
green	A
blue	A
red	B
brown	C
orange	D
pink	E
purple	E

Final edited matrix / .txt file

Gene	green	blue	red	brown	pink	purple	orange
A	1	1	0	0	0	0	0
B	0	0	1	0	0	0	0
C	0	1	0	0	0	0	0
D	0	0	0	0	0	0	1
E	0	0	0	0	1	1	0

!!! How can I get the final matrix to contain '1' and '0' values, where '1' indicates that the gene has a corresponding phenotype, while '0' says it does not?
