If you’re working with NumPy arrays, you can convert all float elements to integers: import numpy as np float_array = np.array([1.5, 2.7, 3.9]) int_array = float_array.astype(int) print(int_array) # Output: [1 2 3] ReadHow to Read XML Files in Python? Comparison of Methods He...
# install numpy pip install numpy # import numpy import numpy as npNext, we will use np.array() function to convert the list of floats to integer.int_list = np.array(float_list).astype(int).tolist() print(int_list) # [1, 3, 5]...

# 报错位置inst_com[0]=int(inst_com[0]+0.5)inst_com[1]=int(inst_com[1]+0.5) 二、尝试解决 试了一些判断方法,无论是使用python内置的nan还是np.nan都无效,依旧会报错: # 尝试解决方法(无效)ifinst_com[0]==float(np.NaN)orinst_com[1]==float(np.NaN):continue ...
df = df.astype({"Fee":"int","Discount":"int"}) # Example 6: Convert "Fee" from float # To int and replace NaN values df['Fee'] = df['Fee'].fillna(0).astype(int) print(df.dtypes) To run some examples of converting the column to integer dtype in Pandas DataFrame, let’s cr...
在使用NumPy时,如果遇到“could not convert string to float”的错误,通常是因为尝试将字符串类型的值转换为浮点数,但字符串中包含无法转换为浮点数的字符。 原因分析 数据类型不匹配: 当使用np.loadtxt()或其他函数读取数据时,如果文件中包含非数字字符(如字母、空格、特殊符号等),并且没有正确设置dtype或conver...
