How can pandas convert strings into numbers?

In Pandas, you can convert strings to numbers using the astype() function. The specific steps are as follows:

1. Create a Pandas Series or DataFrame that contains strings.
2. convert to a specific data type
3. integer
4. 1. a fluid material that can only partially cover a solid surface

Here is an example code:

import pandas as pd

# 创建一个包含字符串的Series
s = pd.Series(['10', '20', '30', '40'])

# 将字符串转换为整数
s = s.astype(int)

# 打印转换后的Series
print(s)

The output is:

0    10
1    20
2    30
3    40
dtype: int64

In the example above, use astype(int) to convert a string into an integer. If you want to convert a string into a float, you can use astype(float).
