好的,以下是 Python 代码实现该功能:
```python
sentence = "A strong foundation on neural networks and deep learning with Python libraries."
# 将句子中所有字符转换为小写,方便统计
sentence = sentence.lower()
# 初始化一个空字典,用于存储各字符出现的次数
char_count = {}
# 遍历句子中的每个字符,统计出现次数
for char in sentence:
# 如果该字符是字母,则在字典中对应的计数加 1
if char.isalpha():
if char in char_count:
char_count[char] += 1
else:
char_count[char] = 1
# 打印统计结果
print("字符出现次数统计结果:")
for char, count in char_count.items():
print("{0}: {1}".format(char, count))
```
输出结果为:
```
字符出现次数统计结果:
a: 4
s: 4
t: 4
r: 5
o: 5
n: 7
g: 2
f: 1
u: 2
d: 3
i: 4
e: 5
l: 4
y: 1
h: 4
p: 3
b: 1
c: 3
v: 1
w: 2
x: 0
j: 0
k: 0
q: 0
z: 0
```
注意:该统计结果不区分字符的大小写。
