从txt文件中将字符存储在矩阵中

# 1. 读取txt文件
with open('file.txt', 'r') as f:
    file_content = f.read()

# 2. 解析文件内容
characters = []
for char in file_content:
    if char.isalpha():  # 只提取字母字符
        characters.append(char)

# 3. 创建矩阵
num_rows = 5  # 矩阵的行数
num_cols = (len(characters) + num_rows - 1) // num_rows  # 矩阵的列数
matrix = [[''] * num_cols for _ in range(num_rows)]

# 4. 将字符存储在矩阵中
for i, char in enumerate(characters):
    row = i % num_rows
    col = i // num_rows
    matrix[row][col] = char

# 打印矩阵
for row in matrix:
    print(' '.join(row))
