请用python代码生成接枝纳米小球模型的lammps的data文件

您好，我能为您提供一个生成接枝纳米小球模型的lammps的data文件的python代码：

import numpy as np

# 首先需要定义纳米小球的直径和总数
diameter = 2.0 # 纳米小球的直径
num_balls = 100 # 纳米小球的数量

# 计算纳米小球的体积
volume = 4.0 / 3.0 * np.pi * (diameter / 2.0)**3

# 定义接枝纳米小球的模型的基本信息
model_name = "nanoballs"
num_atoms = num_balls
num_bonds = 0
num_angles = 0
num_dihedrals = 0

# 定义纳米小球的原子类型
atom_type = 1

# 定义纳米小球的质量
mass = 1.0

# 定义模拟的盒子的大小
xlo = 0.0
xhi = 10.0
ylo = 0.0
yhi = 10.0
zlo = 0.0
zhi = 10.0

# 开始生成data文件的内容
output = ""
output += "{}\n".format(model_name)
output += "{} atoms\n".format(num_atoms)
output += "{} bonds\n".format(num_bonds)
output += "{} angles\n".format(num_angles)
output += "{} dihedrals\n".format(num_dihedrals)
output += "\n"
output += "{} atom types\n".format(atom_type)
output += "\n"
output += "{} {} xlo xhi\n".format(xlo, xhi)
output += "{} {} ylo yhi\n".format(ylo, yhi)
output += "{} {} zlo zhi\n".format(zlo, zhi)
output += "\n"
output += "Masses\n"
output += "\n"
output += "1 {}\n".format(mass)
output += "\n"
output += "Atoms\n"
output += "\n"

# 生成纳米小球的位置
for i in range(num_balls):
  x = np.random.uniform(xlo, xhi)
  y = np.random.uniform(ylo, yhi)
  z = np.random.uniform(zlo, zhi)
  output += "{} {} {}
