"Tricks" to read Excel data file with Python

Use Python to read Excel data, save the data in each row to the dict dictionary, and finally save the dictionary to the list in.

Installation Library

My demand is to read excel file, so first pip install xlrd

Obtain

I have two self Sheet , as shown:


You can get "Campus Files" in the following three ways:

rbook = xlrd.open_workbook('test1.xlsx')  # 打开excel，创建一个workbook对象
table = rbook.sheet_by_name("校园档案")  # 通过名称获取
# table = rbook.sheets()[1]  # 通过索引顺序获取，注意是从0开始
# table = rbook.sheet_by_index(1)  # 通过索引顺序获取

Operating line & column

• Obtain a valid number of rows in the table

num_rows = table.nrows  # 获取该sheet中的有效行数
print("该表共有%d行" % num_rows)

• Gets the value of the second row

print(table.row_values(rowx=1))

• Gets the value of a cell, enter it coordinates

print(table.cell_value(rowx=2, colx=1))

For column operation, all of the code need only above the row into col can.

Save circulation to the dictionary

Each row of data will be saved to the dict dictionary, the dictionary is added to the final list of:

# 获取一个sheet
rbook = xlrd.open_workbook('test1.xlsx')  # 打开excel，创建一个workbook对象 厦门鹭江宾馆
table = rbook.sheets()[1]  # 通过索引顺序获取，注意是从0开始

# 循环获取
list = []  # 将所有数据汇总成一个list
num_rows = table.nrows  # 获取该sheet中的有效行数
col_names = table.row_values(0)  # 获取行数下标为0也就是第一行的数据值（表头）
print("该表共有%d行" % num_rows)
for row_num in range(1, num_rows):
    row = table.row_values(row_num)  # 获取每一行的数据值
    if row:
        dict = {}
        for i in range(len(col_names)):
            dict[col_names[i]] = row[i]
        list.append(dict)
print(list)
