How to replace a zero integer with an empty string in python?

Question

In the following code I would like the CHAC to show an empty string so that I can concatenate it with similar strings later.

def __init__(self, **kwargs):
    self.id = random.randint(self.min_hit_points, self.max_hit_points)
    self.level = random.randint(self.min_level, self.max_level)
    self.CHAC = str(int(self.id / 5 - 1 * (self.level - 1))) 
    self.color = random.choice(COLORS)

The easy way is self.CHAC = "" if self.CHAC=='0' else self.CHAC — Tim Roberts

Since integer zero is falsy, you can do

str(int(self.id / 5 - 1 * (self.level - 1)) or '')

You can use a conditional expression:

value = int(self.id/5-1*(self.level-1))
self.CHAC = '' if value == 0 else str(value)
