Use try and except methods:

try:

.......

...your code

..

except:

...to capture errors...

As Jaanvi is saying, use try .. except.

There are cases where if .. else might work too, but try .. except is a better option, I think.

Let's say you want to devide 2 numbers. In this case you might get ZeroDivisionError.

a = 10
b = 0

# for a / b will generate a ZeroDivisionError on runtime
# to prevent the crash:
try:
    res = a / b
except ZeroDivisionError e:
    # for negative value you will get -inf
    # for positive value you will get inf
    res = a * float('inf')
  
    # print the error, if you want to see it
    print(e)
except: 
    # this will catch any remaining errors
    print('Other errors')
