遍历Python和Pandas循环有多种解决方法,以下是其中几种常用的方法和代码示例:
numbers = [1, 2, 3, 4, 5]
for num in numbers:
print(num)
import pandas as pd
data = {'Name': ['John', 'Emma', 'Tom'],
'Age': [25, 30, 35]}
df = pd.DataFrame(data)
for index, row in df.iterrows():
print(row['Name'], row['Age'])
import pandas as pd
data = {'Name': ['John', 'Emma', 'Tom'],
'Age': [25, 30, 35]}
df = pd.DataFrame(data)
for column in df.columns:
print(column)
print(df[column])
numbers = [1, 2, 3, 4, 5]
squared_numbers = [num ** 2 for num in numbers]
print(squared_numbers)
import pandas as pd
data = {'Name': ['John', 'Emma', 'Tom'],
'Age': [25, 30, 35]}
df = pd.DataFrame(data)
def process_row(row):
return row['Name'] + ' is ' + str(row['Age']) + ' years old'
df['Description'] = df.apply(process_row, axis=1)
print(df['Description'])
这些是遍历Python和Pandas循环的几种常用方法和代码示例。根据具体需求和情况,你可以选择适合的方法来遍历数据。
