del_del

Given a string, if the string “del” appears starting at index 1, return a string where that “del” has been deleted. Otherwise, return the string unchanged.

del_del("adelbc") -> "abc"
del_del("adelHello") -> "aHello"
del_del("adedbc") -> "adedbc"

This exercise was taken from codingbat.com and has been adapted for the Python language. There are many great programming exercises there, but the majority are created for Java.

Starter Code

def del_del(string: str) -> str:
    pass


result = del_del('adelbc')
print(result)
