Python |从给定的表达式列表中生成个性化数据
原文:https://www . geesforgeks . org/python-生成-个性化-数据-来自给定的表达式列表/
给定不同的表达式列表，任务是在 csv 文件中为某些目的生成这些表达式的随机组合，例如测试数据库，这与序数数据模拟器相反，序数数据模拟器从随机数和标准名称生成数据集。
例:
Input :lists of your own expressions
Names = ['David', 'Emilia', 'John', 'Karmen'],
Hobbies = ['Hiking', 'football', 'Gaming', 'Skydiving'],
skills = ['Communication', 'leadership', 'cooking']
Output : a csv file with a random combination of expressions
Names, Age, Hobbies, skills
Emilia, 54, "['football', 'Hiking']", leadership
David, 22, "['Skydiving', 'Gaming']", cooking
Emilia, 59, "['football', 'Skydiving']", leadership
Emilia, 45, "['Gaming', 'football']", leadership
David, 62, "['Hiking', 'football']", cooking
David, 56, "['football', 'Hiking']", leadership
John, 17, "['Gaming', 'football']", cooking
David, 28, "['Gaming', 'football']", leadership
David, 28, "['Skydiving', 'football']", cooking
John, 17, "['Gaming', 'Skydiving']", cooking
John, 61, "['Hiking', 'football']", cooking
John, 44, "['Hiking', 'Gaming']", leadership
Emilia, 17, "['Hiking', 'Gaming']", Communication
Karmen, 34, "['football', 'Skydiving']", leadership
Emilia, 65, "['football', 'Hiking']", leadership
代码:生成个性化数据
# importing libraries
import csv
import random
# create a csv file named "abc" that contains our dataset
with open('abc.csv', 'w', newline ='') as f:
file = csv.writer(f)
file.writerow(['Names', 'Age', 'Hobbies', 'skills'])
# generate rows as much as wanted
for i in range (1, 10) :
Names =['David', 'Emilia', 'John', 'Karmen']
Hobbies =['Hiking', 'football', 'Gaming', 'Skydiving']
skills =['Communication', 'leadership', 'cooking']
file.writerow([random.choice(Names), random.randint(17, 65),
random.sample(Hobbies, 2), random.choice(skills)])
