在特定行数拆分字符串

def split_string_by_lines(string, num_lines):
    max_chars_per_line = -(-len(string) // num_lines)  # 向上取整计算每行的最大字符数
    lines = []
    for i in range(0, len(string), max_chars_per_line):
        lines.append(string[i:i+max_chars_per_line])  # 按照最大字符数拆分字符串并添加到列表中
    return lines

# 示例用法
string = "This is a long string that needs to be split into multiple lines."
num_lines = 4
result = split_string_by_lines(string, num_lines)
for line in result:
    print(line)

This is a long
 string that n
eeds to be spl
it into multipl
e lines.
