Identify the invalid Python statement from the following:
Show Hint
To initialize an empty dictionary, use dict()} or \{\}}. Avoid mixing the two syntax forms.
Updated On: Jan 13, 2026
d = dict()
e = {}
f = []
g = dict{}
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The statement g = dict{} is invalid because the dict() function should not include curly braces {} as an argument. The correct way to initialize an empty dictionary is g = dict() or g = {}. All other options correctly initialize dictionaries or lists.

- State True or False:
While defining a function in Python, the positional parameters in the function header must always be written after the default parameters. The SELECT statement when combined with \(\_\_\_\_\_\_\) clause, returns records without repetition.
- What will be the output of the following statement:
print(16 * 5 / 4 * 2 / 5 - 8)
- The slicing operations in the given code work as follows:
myStr[:4]extracts the first 4 characters, which are"MISS".myStr[-5:]extracts the last 5 characters, which are"SIPPI".- These two substrings are concatenated with a
"#"in between, resulting in"MISS#SIPPI".
In SQL, the aggregate function which will display the cardinality of the table is \(\_\_\_\_\_\).
