Q.Ravi, a Python programmer, is working on a project in which he wants to write a function to count the number of even and odd values in the list. He has written the following code but his code is having errors. Rewrite the correct code and underline the corrections made. define EOCOUNT(L): even_no=odd_no=0 for i in range(0,len(L)) if L[i]%2=0: even_no+=1 Else: odd_no+=1 print(even_no, odd_no)

The corrected function properly counts even and odd numbers by iterating through the list with correct Python syntax.
The problem tests your understanding of Python function syntax and control structures. A function definition requires the def keyword, control statements (for, if) need colons, comparison uses == (not =), and Python keywords are case-sensitive.
Let me walk through each error and its fix:
-
Function definition keyword
The line
define EOCOUNT(L):is incorrect because Python usesdef, notdefine, to declare functions. The correct syntax isdef EOCOUNT(L):. -
Missing colon after
forstatementThe line
for i in range(0,len(L))is missing a colon at the end. Every compound statement in Python (loops, conditionals, function definitions) must end with a colon. It should befor i in range(0,len(L)):. -
Assignment vs. comparison operator
The condition
if L[i]%2=0:uses a single=(assignment operator) instead of==(comparison operator). In Python,=assigns values while==tests equality. The correct condition isif L[i]%2==0:. -
Incorrect capitalization of
elsePython keywords are case-sensitive and must be lowercase.
Else:should beelse:. …
