Python: Find the maximum occurring character in a given string

Python String: Exercise-59 with Solution

Write a Python program to find the maximum occurring character in a given string.

Sample Solution:-

Python Code:

def get_max_occuring_char(str1):
  ASCII_SIZE = 256
  ctr = [0] * ASCII_SIZE
  max = -1
  ch = ''
  for i in str1:
  for i in str1:
    if max < ctr[ord(i)]:
      max = ctr[ord(i)]
      ch = i
  return ch

print(get_max_occuring_char("Python: Get file creation and modification date/times"))

Sample Output:

Python: Tips of the Day

Check if a given key already exists in a dictionary:

In is the intended way to test for the existence of a key in a dict.

d = {"key1": 10, "key2": 23}

if "key1" in d:
    print("this will execute")

if "nonexistent key" in d:
    print("this will not")

If you wanted a default, you can always use dict.get():

d = dict()

for i in range(100):
    key = i % 10
    d[key] = d.get(key, 0) + 1

and if you wanted to always ensure a default value for any key you can either use dict.setdefault() repeatedly or defaultdict from the collections module, like so:

from collections import defaultdict

d = defaultdict(int)

for i in range(100):
    d[i % 10] += 1

but in general, the in keyword is the best way to do it.
