编写一个 Python 程序，使用 for 循环和字典来计算字符串中的字符频率。在这个 Python 示例中，for 循环迭代整个字符串。我们把所有的字符数分配给字典键。
# Count Charcaters Frequency in a String
string = input("Please enter the Your Own String = ")
chardict = {}
for num in string:
keys = chardict.keys()
if num in keys:
chardict[num] += 1
else:
chardict[num] = 1
print(chardict)这个 Python 程序使用 Counter 集合对给定字符串中的所有字符频率进行计数。
# Count Charcaters Frequency in a String
from collections import Counter
string = input("Please enter the Your Own String = ")
chars = Counter(string)
print("Total Characters Frequency in this String = ")
print(chars)Please enter the Your Own String = hello python programmers
Total Characters Frequency in this String =
Counter({'o': 3, 'r': 3, 'h': 2, 'e': 2, 'l': 2, ' ': 2, 'p': 2, 'm': 2, 'y': 1, 't': 1, 'n': 1, 'g': 1, 'a': 1, 's': 1})原创文章，作者：MO4YX，如若转载，请注明出处：https://www.506064.com/n/130141.html
