How to count the number of different characters using python

How to count the number of times different characters appear in a string?

Then use the powerful python to solve it!

Example

#统计不同字符的次数

str_1 = input("请输入一串字符：")

result = {}

for i in str_1:
    result[i] = str_1.count(i)

print(result)

Output result

请输入一串字符：afbvssevsbrfnvb
{'a': 1, 'f': 2, 'b': 3, 'v': 3, 's': 3, 'e': 1, 'r': 1, 'n': 1}

Analysis: First, we use the input function to obtain the user's input, and at the same time create an empty dictionary result for storage Statistical results; secondly, use a for loop to traverse the user's input, add the traversal results and statistical results to the result, print the result, and realize the statistics of the number of characters.
