1.前言

近期要用excel统计学生成绩与统计，但网上找不到学生成绩的数据所以就用python生成了，记录一下。

2.生成姓名和学号，科目

from openpyxl import Workbook, load_workbook
from faker import Faker

#xlsx表格地址
path = r"C:\Users\clover\Desktop\1.xlsx"
# 创建一个 workbook
wb = load_workbook(filename=path)
# # 获取被激活的 worksheet
ws = wb['Sheet1']
# 设置生成姓名的地区
fake = Faker("zh_CN")

# 设置单元格内容
ws['A1'] = "学号"
ws['B1'] = "姓名"
ws['C1'] = "语文"
ws['D1'] = "数学"
ws['E1'] = "英语"
ws['F1'] = "物理"
ws['G1'] = "地理"
ws['H1'] = "化学"
ws['I1'] = "生物"
ws['J1'] = "政治"
ws['K1'] = "历史"

# 生成学号
sjs = 0
# 生成的个数
for i in range(2,52):
    ws[f"A{i}"] = "2021D001"+ "%02d"%(sjs)
    sjs += 1

# 生成姓名
for k in range(2,52):
    ws[f"B{k}"] = fake.name()

这里要安装2个库

pip install openpyxl
pip install faker

3.生成分数

一开始是用自带的random生成的但发现一个问题，生成的数不符合真实的的情况，生成的数据全部在0-59分这个区间，后面查了资料发现学生成绩是呈正太分布的，既然是正太分布那就用numpy这个库生成正太分布的随机数。下面是代码。

pip install numpy

import numpy as np

# 生成正太分布的0-100的随机整数
def get_random():
    mean = 75    # 正态分布的均值
    std = 11   # 正态分布的标准差
    size = 50   # 生成随机数的个数
    # 生成正态分布的随机数
    random_nums = np.random.normal(mean, std, size)
    # 将随机数限制在0到100之间
    random_nums = np.clip(random_nums, 0, 100)
    # 将随机数转换为整数
    integer_nums = random_nums.astype(int)
    return integer_nums

4.全部代码

from openpyxl import Workbook, load_workbook
import random
import datetime
from faker import Faker
import numpy as np

# 生成正太分布的0-100的随机整数
def get_random():
    mean = 75    # 正态分布的均值
    std = 11   # 正态分布的标准差
    size = 50   # 生成随机数的个数
    # 生成正态分布的随机数
    random_nums = np.random.normal(mean, std, size)
    # 将随机数限制在0到100之间
    random_nums = np.clip(random_nums, 0, 100)
    # 将随机数转换为整数
    integer_nums = random_nums.astype(int)
    return integer_nums


#xlsx表格地址
path = r"C:\Users\clover\Desktop\1.xlsx"
# 创建一个 workbook
wb = load_workbook(filename=path)
# # 获取被激活的 worksheet
ws = wb['Sheet1']

# 设置生成姓名的地区
fake = Faker("zh_CN")

# 设置单元格内容
ws['A1'] = "学号"
ws['B1'] = "姓名"
ws['C1'] = "语文"
ws['D1'] = "数学"
ws['E1'] = "英语"
ws['F1'] = "物理"
ws['G1'] = "地理"
ws['H1'] = "化学"
ws['I1'] = "生物"
ws['J1'] = "政治"
ws['K1'] = "历史"

# 生成学号
sjs = 0
# 生成的个数
for i in range(2,52):
    ws[f"A{i}"] = "2021D001"+ "%02d"%(sjs)
    sjs += 1

# 生成姓名
for k in range(2,52):
    ws[f"B{k}"] = fake.name()


l = ["C","D","E","F","G","H","I","J","K"]




for z in l:
    a = 2
    data = get_random()
    for i in data:
        ws[f"{z}{a}"] = i
        a += 1




# # 设置一行内容
# # 保存 Excel 文件
wb.save(r"C:\Users\clover\Desktop\2.xlsx")
