To find the index of an element in the list in Python, we can also use theforloop method. The code is: consonants=["b","f","g","h","j","k"]check="j"position=-1foriinrange(len(consonants)):ifconsonants[i]==check:position=ibreakifposition>-1:print("Element's Index in the ...
We also have theindex()function in Python that returns the index of the given element if it is present in the list. If not, then it throws aValueError. To get the index of the maximum element in a list, we will first find the maximum element with themax()function and find its index...
method. To use theindex()method, you just need to pass the element as an argument. Definition and Usage:Thelist.index(value)method returns the index of thevalueargument in thelist. You can use optionalstartandstoparguments to limit the index range where to search for the value in the list...
Python program to index every element in a list except one# Import numpy import numpy as np # Creating a numpy array arr = np.array([0, 1, 2, 3, 4, 5]) # Display original array print("Original Array:\n",arr,"\n") # Defining an empty list res = [] # Looping over arr to...
When we refer to a particular index number of a string, Python returns the character that is in that position. Since the letteryis at index number 4 of the stringss = "Sammy Shark!", when we printss[4]we receiveyas the output. ...
mylist = ['Python', 'Spark', 'Hadoop'] # Get IndexError in for loop with range() for i in range(4): print(mylist[i]) Yields the same output as above. You can fix IndexError in the above code using thelen()function. 3. How to Fix IndexError(List Index Out of Range) ...
Python developers often find themselves in a position where they want to choose printing over logging. Print statements are easy to use but they don’t come with a load of features that Python Logging modules comes with. Some developers use the print statement to ensure the code works without...

This first creates a range corresponding to the indexes in our list (0tolen(colors) - 1). We can loop over this range using Python’s for-in loop (really aforeach). This provides us with the index of each item in ourcolorslist, which is the same way that C-styleforloops work. ...
