I want to create 50 random arrays and put them all in a dataframe. I'm realizing now that i should just do completeDF = pd.DataFrame(np.random.randint(0,100,size=(50, 10))) but this is just for practice / fun. My question isn't about the efficiency of what i'm doing. My question is about how jupyter and spyder are behaving weird. I've restarted them both before trying this.
我的问题是：
1) Why does jupyter and spyder think that i=0 is invalid syntax?
2）突然间，当我在第1行按Enter进入第2行时，它将光标6的选项卡带到应该位于的右边。为什么会这样？我怎么做才能使jupyter和spyder像这样？如果我将这段代码复制并粘贴到Spyder中，它将执行相同的操作。我已经在同一个Jupyter笔记本电脑中玩过熊猫和Numpy了一段时间，但它只是在这个单元中开始进行。其他细胞都很好。
在另一个单元格中，下面的简单代码执行得很好，并且当我转到下一行时，光标不会出现问题。
i=0
while i < 50:
print(i)
i+=1
这是给我带来问题的代码：
import numpy as np
import pandas as pd
# define completeDF to start with
np.random.seed(0)
completeDF = pd.DataFrame(np.random.randint(0,100,size=(1, 10),dtype=int)
while i < 50:
i=1
np.random.seed(i)
randomTen = np.random.randint(0,101,10) # rndomTen is an array
randomTenisDF = pd.DataFrame(randomTen)
completeDF= pd.concat([completeDF], [randomTenisDF])
i=i+1
print(completeDF)
输出：
File "<ipython-input-11-f043bd7555e6>", line 9
while i < 50:
^
SyntaxError: invalid syntax
if I put i=1 right before the while loop, the output is:
File "<ipython-input-7-6b075a188843>", line 8
i=1
^
SyntaxError: invalid syntax
The only solution i can think of if i see a cell behaving this way is to manually copy everything from the weird cell into a new cell. Copying and pasting into a new cell doesn't get rid of the weird extra tabs issue and the not accepting of i=0 syntax.
