split pandas dataframe into train and test code example
Example 1: train test split pandas
from sklearn.model_selection import train_test_split
train, test = train_test_split(df, test_size=0.2)
Example 2: pandas split dataframe to train and test
train=df.sample(frac=0.8,random_state=200)
test=df.drop(train.index)
Example 3: pandas split train test
from sklearn.model_selection import train_test_split
y = df.pop('output')
X = df
X_train,X_test,y_train,y_test = train_test_split(X.index,y,test_size=0.2)
X.iloc[X_train]
Example 4: train-test split code in pandas
df_permutated = df.sample(frac=1)
train_size = 0.8
train_end = int(len(df_permutated)*train_size)
df_train = df_permutated[:train_end]
df_test = df_permutated[train_end:]
