使用 for 循环计算用户输入中的单个字母

发布于 2025-01-09 01:32:30 字数 300 浏览 3 评论 0原文

我正在努力完成一项任务，计算用户输入中的字母并返回在输入的句子中可以找到该字母的次数。

这就是我到目前为止所得到的：

sentence = input("write an sentence here: ")

count = 0

for character in sentence:
    if e in character:
        count += 1
    print count

我收到错误。将不胜感激任何帮助。

I am struggling with a task, counting a letter from a user input and returning the number of times the letter can be found within the sentence from the input.

this is what I have so far:

sentence = input("write an sentence here: ")

count = 0

for character in sentence:
    if e in character:
        count += 1
    print count

I am getting errors. Would appreciate any help.

如果您只想计算字符串中的所有字母（不带空格），那么这里就可以了：

import string
letters = string.ascii_lowercase
sentence = input("write an sentence here: ")
count = 0

for letter in sentence:
    if letter in letters:
        count+=1
print(count)

如果您想搜索某个字母：


sentence = input("write an sentence here: ")
count = 0
searchedletter= input("Put your searched letter: ")
for letter in sentence:
    if letter==searchedletter:
        count+=1
print(count)

If you just want to count all the letters in string, without spaces, then here you have it:

import string
letters = string.ascii_lowercase
sentence = input("write an sentence here: ")
count = 0

for letter in sentence:
    if letter in letters:
        count+=1
print(count)

If you want to search for a certain letter:


sentence = input("write an sentence here: ")
count = 0
searchedletter= input("Put your searched letter: ")
for letter in sentence:
    if letter==searchedletter:
        count+=1
print(count)
