1.CSV文件格式

要在文本文件中存储数据，最简单的方式是将数据作为一系列以逗号分隔的值（CSV）写入文件。这样的文件称为CSV文件。如下是一行CSV格式的天气数据：

2014-3-2,35,31,26,5,1,-2,36,29,23,29.84,29.79,29.74,10,10,10,15,8,,0.00,0,,82

这是某地2014年3月2号的天气数据，其中包含当天的最高气温和最低气温，还有众多其他数据。CSV文件对人来说难以阅读，但程序可轻松的对其进行处理，这有助于加快数据分析的过程。

（2）分析CSV文件头

csv模块包含在Python标准库中，可用于分析CSV文件中的数据行，让我们能够快速提取感兴趣的值。

import csv

filename = 'sitka_weather_07-2014.csv'
with open(filename) as f:
    reader = csv.reader(f)         #创建一个与该文件相关联的阅读器对象
    header_row = next(reader)      # 模块csv的reader类包含next()方法，表用时返回文件的下一行
                                   #因为就调用一次next()方法，所以返回文件的第一行
    print(header_row)

reader处理文件中以逗号分隔的第一行数据，并将每项数据都作为一个元素存储在列表中。
文件头AKDT表示阿拉斯加时间，其位置标明每行的第一个值都是日期或时间。
文件头Max TemperatureF指出每行的第二个值都是当天的最高华氏气温…

（3）打印文件头及其位置

（4）提取，读取每天最高气温数据并绘制气温图表

①首先读取每天的最高气温：

highs = []
for row in reader:
	high = int(row[1])
	highs.append(high)
print(highs)

阅读器对象从其停留的地方继续往下读取CSV文件，每次都自动返回当前所处位置的下一行。由于我们已经读取了文件头行，这个循环将从第二行开始------从这行开始包含的是实际数据。

②然后使用matplotlib进行可视化操作：

import csv
from matplotlib import pyplot as plt

filename = 'sitka_weather_07-2014.csv'
with open(filename) as f:
    reader = csv.reader(f)         #创建一个与该文件相关联的阅读器对象
    header_row = next(reader)      # 模块csv的reader类包含next()方法，表用时返回文件的下一行
                                   #因为就调用一次next()方法，所以返回文件的第一行

    # for index,column_header in enumerate(header_row):   #对列表调用enumerate()方法，获取每个元素的索引及其值
    #    print(index,column_header)

    #获取日期和最高气温
    highs = []
    for row in reader:
        high = int(row[1])
        highs.append(high)
    print(highs)

    #根据数据绘制图形
    fig = plt.figure(dpi=128,figsize=(10,6))        #设置绘图窗口的尺寸
    plt.plot(highs,c='red')

    #设置图形的格式
    plt.title("Daily high temperatures, July 2014", fontsize=24)
    plt.xlabel('',fontsize=16)
    plt.ylabel("Temperature(F)",fontsize=16)
    plt.tick_params(axis='both',which='major',labelsize=16)

    plt.show()

（5）在图表中添加日期数据

①首先，分析：读取天气数据文件中日期数据时，获得的是一个字符串，因此我们需要将字符串‘2014-7-1’转换为一个表示相应日期的对象。为了创建一个表示2014年7月1日的对象，可使用模块datetime中的方法strptime()。

方法strptime()将包含所需日期的字符串作为第一个实参；第二个实参告诉python如何设置日期的格式。
方法strptime()可接受各种实参，并根据它们来决定如何解读日期。

②在图表中添加日期：

import csv
from matplotlib import pyplot as plt
from datetime import datetime

'''处理少量csv数据时！'''

filename = 'sitka_weather_07-2014.csv'
with open(filename) as f:
    reader = csv.reader(f)         #创建一个与该文件相关联的阅读器对象
    header_row = next(reader)      # 模块csv的reader类包含next()方法，表用时返回文件的下一行
                                   #因为就调用一次next()方法，所以返回文件的第一行

    # for index,column_header in enumerate(header_row):   #对列表调用enumerate()方法，获取每个元素的索引及其值
    #    print(index,column_header)

    #获取日期和最高气温
    dates,highs =[],[]
    for row in reader:              #依此循环csv文件的每一行
        current_date = datetime.strptime(row[0],"%Y-%m-%d")    #取出每一行的下标为0的数据
        dates.append(current_date)
        high = int(row[1])          #循环的每一行数据为列表形式存在row里，取出每一行的下标为1的数据
        highs.append(high)

    #根据数据绘制图形
    fig = plt.figure(dpi=128,figsize=(10,6))        #设置绘图窗口的尺寸
    plt.plot(dates,highs,c='red')

    #设置图形的格式
    plt.title("Daily high temperatures, July 2014", fontsize=24)
    plt.xlabel('',fontsize=16)
    fig.autofmt_xdate()   #使x轴标签绘制为斜的日期标签，以免它们彼此重叠
    plt.ylabel("Temperature(F)",fontsize=16)
    plt.tick_params(axis='both',which='major',labelsize=16)

    plt.show()

（2）使用如上数据进行上述操作

只需更改filename变量名即图表标题即可：

（3）再绘制一个数据系列（添加最低气温数据）

import csv
from matplotlib import pyplot as plt
from datetime import datetime

'''处理大量数据时，同时画出多个折线！'''

filename = 'sitka_weather_2014.csv'
with open(filename) as f:
    reader = csv.reader(f)         #创建一个与该文件相关联的阅读器对象
    header_row = next(reader)      # 模块csv的reader类包含next()方法，表用时返回文件的下一行
                                   #因为就调用一次next()方法，所以返回文件的第一行

    #for index,column_header in enumerate(header_row):   #对列表调用enumerate()方法，获取每个元素的索引及其值
    #    print(index,column_header)

    #获取日期和最高气温,最低气温
    dates,highs,lows =[],[],[]
    for row in reader:              #依此循环csv文件的每一行
        current_date = datetime.strptime(row[0],"%Y-%m-%d")    #s取出每一行的下标为0的数据
        dates.append(current_date)

        high = int(row[1])          #循环的每一行为列表形式存在在row里，取出每一行的下标为1的数据
        highs.append(high)

        low = int(row[3])
        lows.append(low)

    #根据数据绘制图形
    fig = plt.figure(dpi=128,figsize=(10,6))        #设置绘图窗口的尺寸
    plt.plot(dates,highs,c='red')
    plt.plot(dates,lows,c='blue')

    #设置图形的格式
    plt.title("Daily high and low temperatures - 2014", fontsize=24)
    plt.xlabel('',fontsize=16)
    fig.autofmt_xdate()   #使x轴标签绘制为斜的日期标签，以免它们彼此重叠
    plt.ylabel("Temperature(F)",fontsize=16)
    plt.tick_params(axis='both',which='major',labelsize=16)

    plt.show()

（4）给图表区域着色

我们将使用方法fill_between()，它接收一个x值系列和两个y值系列，并填充两个y值系列之间的空间。

import csv
from matplotlib import pyplot as plt
from datetime import datetime

'''处理大量数据时，同时画出多个折线！'''

filename = 'sitka_weather_2014.csv'
with open(filename) as f:
    reader = csv.reader(f)         #创建一个与该文件相关联的阅读器对象
    header_row = next(reader)      # 模块csv的reader类包含next()方法，表用时返回文件的下一行
                                   #因为就调用一次next()方法，所以返回文件的第一行

    #for index,column_header in enumerate(header_row):   #对列表调用enumerate()方法，获取每个元素的索引及其值
    #    print(index,column_header)

    #获取日期和最高气温,最低气温
    dates,highs,lows =[],[],[]
    for row in reader:              #依此循环csv文件的每一行
        current_date = datetime.strptime(row[0],"%Y-%m-%d")    #s取出每一行的下标为0的数据
        dates.append(current_date)

        high = int(row[1])          #循环的每一行为列表形式存在在row里，取出每一行的下标为1的数据
        highs.append(high)

        low = int(row[3])
        lows.append(low)

    #根据数据绘制图形
    fig = plt.figure(dpi=128,figsize=(10,6))        #设置绘图窗口的尺寸
    plt.plot(dates,highs,c='red',alpha=0.5)         #alpha设置颜色的透明度。0是完全透明；1是完全不透明
    plt.plot(dates,lows,c='blue',alpha=0.5)
    #fill_between()接收一个x值系列和两个y值系列，并填充两个y值系列之间的空间。
    plt.fill_between(dates,highs,lows,facecolor='blue',alpha=0.1)

    #设置图形的格式
    plt.title("Daily high and low temperatures - 2014", fontsize=24)
    plt.xlabel('',fontsize=16)
    fig.autofmt_xdate()   #使x轴标签绘制为斜的日期标签，以免它们彼此重叠
    plt.ylabel("Temperature(F)",fontsize=16)
    plt.tick_params(axis='both',which='major',labelsize=16)

    plt.show()

（5）错误检查

我们应该能够使用有关任何地方的天气数据来运行上述代码，但有些气象站会偶尔出现故障，未能收集部分或全部其应该收集的数据。缺失数据可能会引发异常！

比如气温数据中缺失某天的最高温度数据，即此数据中最高温度的字符串为空。这样上述代码运行就会报错！
为解决这种问题，我们在从CSV文件中读取值时执行错误检查代码，对分析数据集时可能出现的异常进行处理：

数据缺失举例：
2014-2-16,,,,,,,,,,,,,,,,,,,0.00,,,-1

import csv
from matplotlib import pyplot as plt
from datetime import datetime

'''如果有些日期部分数据缺失的话，之前的程序会报错无法正常运行！'''

filename = 'death_valley_2014.csv'
with open(filename) as f:
    reader = csv.reader(f)         #创建一个与该文件相关联的阅读器对象
    header_row = next(reader)      # 模块csv的reader类包含next()方法，表用时返回文件的下一行
                                   #因为就调用一次next()方法，所以返回文件的第一行

    #for index,column_header in enumerate(header_row):   #对列表调用enumerate()方法，获取每个元素的索引及其值
    #    print(index,column_header)

    #获取日期和最高气温,最低气温
    dates,highs,lows =[],[],[]
    for row in reader:              #依此循环csv文件的每一行
        try:
            current_date = datetime.strptime(row[0],"%Y-%m-%d")    #s取出每一行的下标为0的数据
            high = int(row[1])          #循环的每一行为列表形式存在在row里，取出每一行的下标为1的数据
            low = int(row[3])
        except ValueError:
            print(current_date,'missing data')
        else:
            highs.append(high)
            dates.append(current_date)
            lows.append(low)

    #根据数据绘制图形
    fig = plt.figure(dpi=128,figsize=(10,6))        #设置绘图窗口的尺寸
    plt.plot(dates,highs,c='red',alpha=0.5)         #alpha设置颜色的透明度。0是完全透明；1是完全不透明
    plt.plot(dates,lows,c='blue',alpha=0.5)
    #fill_between()接收一个x值系列和两个y值系列，并填充两个y值系列之间的空间。
    plt.fill_between(dates,highs,lows,facecolor='blue',alpha=0.1)

    #设置图形的格式
    plt.title("Daily high and low temperatures - 2014\nDeath Valley,CA", fontsize=20)
    plt.xlabel('',fontsize=16)
    fig.autofmt_xdate()   #使x轴标签绘制为斜的日期标签，以免它们彼此重叠
    plt.ylabel("Temperature(F)",fontsize=16)
    plt.tick_params(axis='both',which='major',labelsize=16)

    plt.show()
