我有一个关于将xlsx文件导入Python的基本问题。我已经检查了很多关于同一主题的回复,但是无论我尝试什么,我仍然无法将我的文件导入Python。这是我的代码和我收到的错误:
import pandas as pd
import xlrd
file_location = 'C:\Users\cagdak\Desktop\python_self_learning\Coursera\sample_data.xlsx'
workbook = xlrd.open_workbook(file_location)
错误:
IOError: [Errno 2] No such file or directory: 'C:\\Users\\cagdak\\Desktop\\python_self_learning\\Coursera\\sample_data.xlsx'

使用pandas可以直接获取excel文件的列。这是代码。
import pandas
df = pandas.read_excel('sample.xls')
#print the column names
print df.columns
#get the values for a given column
values = df['collumn_name'].values
#get a data frame with selected columns
FORMAT = ['Col_1', 'Col_2', 'Col_3']
df_selected = df[FORMAT]

您应该使用raw strings or escape your backslash代替,例如:
file_location = r'C:\Users\cagdak\Desktop\python_self_learning\Coursera\sample_data.xlsx'
或
file_location = 'C:\\Users\\cagdak\\Desktop\python_self_learning\\Coursera\\sample_data.xlsx'

继续尝试:
file_location = 'C:/Users/cagdak/Desktop/python_self_learning/Coursera/sample_data.xlsx'
