Answer body :

var = str(input())
var_1 = var.lower()
print (var_1 , sep = "_")

Answer 1

---> sep Issue: sep doesn't do anything here because you're only dealing with one string, not multiple values to separate.

----> Conversion Logic Missing: Your code should include steps to insert underscores before uppercase letters and turn those letters into lowercase.

def camel_to_snake(camel_str):
result = []
for char in camel_str:
if char.isupper():
if result:
result.append('_')
result.append(char.lower())
else:
result.append(char)
return ''.join(result)

var = input().strip()
print(camel_to_snake(var))

Answer 2

You need to have more than one value argument in the print statement before it works, like this......

print(var_1, var_2, sep="_")

Answer 3

Programming is very dangerous 💀

I'm too beginner for this question 😤🥺

however Muhammad Nouman Ali , A͢J ,Jan ,Bob_Li , and Ержан Базаргали thanks alot for your helpful support 🥰

Answer 4

A͢J can please share the sample code 🙂🙏

Answer 5

Naina Kapoor That's because you haven't created a var_2 with a value, but you can also just write...

print(var_1, var_1, sep="_")

Answer 6

Naina Kapoor
you must have more than 1 item to print, otherwise there is nothing to separate.

print(1,2,3,4, sep='_')

in your example, you are only printing var1

Answer 7

Naina Kapoor
you can still use sep if you are just printing the result for a camel to snake conversion.

def c2s(s):
n=0
res=[]
for i,e in enumerate(s):
if e.isupper():
res.append(s[n:i].lower())
n = i
res.append(s[n:].lower())
print(*res, sep='_')

var = input().strip()
c2s(var)

s1 = 'weNeedToConvertToSnakeCase'
c2s(s1)

Answer 8

Bob_Li I'll surely implement this 🥰 but at first I would learn the concept to understand what functions and methods you've used in this program ☺️ your support is really appreciable and I'm grateful for your help 🙏💖

Answer 10

A͢J bhaiya I've inserted the answer below of the question

Answer 11

Naina Kapoor

sep will not work like that

You have to use formatter like this

f"_{var}"

But you have to iterate string and check if a character is in upper case then use formatter to replace that character with _

Answer 12

Jan it is not working 😭😭

Answer 13

Look at the difference:
print("hello!, sep="_" ) #hello
print("hello", "world", sep="_") #hello_world

it's called slicing . it works for lists and strings to chop up parts you need.
