AttributeError: 'str' object has no attribute 'contains'

Question

for i in range(0,len(final3)):
    default=final3["DefaultValue"].iloc[i]
    if (not(default.contains("|"))):
        if(final3["DefaultValue"].iloc[i] in final3["CodedData"].iloc[i]):
            final3["Condition"].iloc[i]="False"
        else:
            final3["Condition"].iloc[i]="True" 

"DefaultValue" column contains values like "1|2|3". So, I tried to split the string using delimiter and check if it exist in the "CodedData" column in the same row. "CodedData" contains values like "3|4" But I am facing the attribute error.

Answer 1

The error message states that you're trying to use .contains() on a string which is not a string function.

Try:

for i in range(0,len(final3)):
    default = final3["DefaultValue"].iloc[i]
    if not "|" in default:
        if default in final3["CodedData"].iloc[i]:
            final3["Condition"].iloc[i] = "False"
        else:
            final3["Condition"].iloc[i] = "True"
