In Example 1, I’ll illustrate how to employ the map function to change the data type of character strings in a list to integer. Have a look at the following Python syntax and its output: my_list_int1=list(map(int,my_list))# Apply map functionprint(my_list_int1)# Print updated li...
it will raise aValueErrorexception. Therefore, it's recommended to use a validation method ortry-catchblock when usingint()for user-entered strings.
Write a Python program to convert a given list of strings into a list of lists using the map function.Sample Solution: Python Code:# Define a function named 'strings_to_listOflists' that takes a list of strings as input def strings_to_listOflists(str): # Use the 'map' function with...

In this example, I’ll explain how to use list comprehensions for the conversion of lists of integers to lists of strings.Have a look at the following Python syntax and its output:sl_str2=[str(x) for x in sl_int] # list comprehension method print(sl_str2) # print output of list ...
Write a Python program to convert a given list of integers and a tuple of integers into a list of strings. Sample Solution: Python Code : # Create a list named 'nums_list' and a tuple named 'nums_tuple' with integer elementsnums_list=[1,2,3,4]nums_tuple=(0,1,2,3)# Print the...

Ensure all the values you’re passing to the function are strings. # Example 1: Integer instead of string date_int = 20230301 date_obj = datetime.datetime.strptime(date_int, '%Y%m%d') # Raises TypeError: strptime() argument 1 must be str, not int # Example 2: List instead of string...
