print("Printing current and previous number and their sum in a range(10)")previous_num = 0# loop from 1 to 10for i in range(1, 11): x_sum = previous_num + i print("Current Number", i, "Previous Number ", previous_num, " Sum: ", x_sum) # modify previous number # set it to the current number previous_num = iExercise 3: Print characters from a string that are present at an even index number
Write a program to accept a string from the user and display characters that are present at an even index number.
For example, str = "pynative" so you should display ‘p’, ‘n’, ‘t’, ‘v’.
Expected Output:
Orginal String is pynativePrinting only even index charspntv
Referencearticle for help: Python Input and Output
Show Hint
- Use Python input() function to accept a string from a user.
- Calculate the length of string using the
len()function - Next, iterate each character of a string using for loop and range() function.
- Use
start = 0, stop = len(s)-1, andstep =2. the step is 2 because we want only even index numbers - in each iteration of a loop, use
s[i]to print character present at current even index number
Show Solution
Solution 1:
# accept input string from a userword = input('Enter word ')print("Original String:", word)# get the length of a stringsize = len(word)# iterate a each character of a string# start: 0 to start with first character# stop: size-1 because index starts with 0# step: 2 to get the characters present at even index like 0, 2, 4print("Printing only even index chars")for i in range(0, size - 1, 2): print("index[", i, "]", word[i])Solution 2: Using list slicing
# accept input string from a userword = input('Enter word ')print("Original String:", word)# using list slicing# convert string to list# pick only even index charsx = list(word)for i in x[0::2]: print(i)Exercise 4: Remove first n characters from a string
Write a program to remove characters from a string starting from zero up to n and return a new string.
For example:
remove_chars("pynative", 4)so output must betive. Here we need to remove first four characters from a string.remove_chars("pynative", 2)so output must benative. Here we need to remove first two characters from a string.
Note: n must be less than the length of the string.
Show Hint
Use string slicing to get the substring. For example, to remove the first four characters and the remeaning use s[4:].
Show Solution
def remove_chars(word, n): print('Original string:', word) x = word[n:] return xprint("Removing characters from a string")print(remove_chars("pynative", 4))print(remove_chars("pynative", 2))Also, try to solvePython String Exercise
