编写python程序，统计一段英文段落中所有字符出现的次数，要求输出9个统计项后换行。

好的，我可以帮你解决这个问题。

以下是 Python 代码示例：

import string

paragraph = "This is a paragraph containing some English words and characters. It has uppercase and lowercase letters, digits, punctuation marks, and even some whitespaces."

# Convert all characters to lowercase for accurate counting
paragraph = paragraph.lower()

# Define a dictionary to hold the count of each character
char_count = {}

# Loop through the paragraph and count each character
for char in paragraph:
    # Only count alphanumeric characters and punctuation marks
    if char in string.ascii_letters + string.digits + string.punctuation:
        if char in char_count:
            char_count[char] += 1
        else:
            char_count[char] = 1

# Print the count of all characters
for char, count in char_count.items():
    print(char, count)

# Print a newline after the output
print()

运行以上代码，你将得到字符计数的输出结果，每行包含一个字符和该字符在段落中出现的次数。

希望这能帮到你。
