## Convert RGB to Hex with Python:

```import re

def rgb_to_hex(rgb_color):
rgb_color = re.search('\(.*\)', rgb_color).group(0).replace(' ', '').lstrip('(').rstrip(')')
[r, g, b] = [int(x) for x in rgb_color.split(',')]
# check if in range 0~255
assert 0 <= r <= 255
assert 0 <= g <= 255
assert 0 <= b <= 255

r = hex(r).lstrip('0x')
g = hex(g).lstrip('0x')
b = hex(b).lstrip('0x')
# re-write '7' to '07'
r = (2 - len(r)) * '0' + r
g = (2 - len(g)) * '0' + g
b = (2 - len(b)) * '0' + b

hex_color = '#' + r + g + b
return hex_color

rgb_input = 'rgb(7,110,190)'
hex_output = rgb_to_hex(rgb_input)
print('Hex color result is:{0}'.format(hex_output))

-------------------
Hex color result is:#076ebe```
