Python Ternary Operator And Assignment In Else

Ternary operator is very useful, why it does not work in this particular case: c='d' d={} d[c]+=1 if c in d else d[c]=1 It gives: d[c]+=1 if c in d else d[c]=1

Solution 1:

The ternary operator works on expressions, not statements. Assignment is a statement. Use a regular if/else.

Solution 2:

The correct way to write this would be:

d[c] = (d[c] + 1) if c in d else 1
